Communication: Verbal, Non-Verbal and Digital Online Information (Definition, Examples and History)

Communication is the process through which an entity, an individual or an organisation conveys information and meaning to one or more recipients through shared signs, producing a verifiable response. The word comes from the Latin communicare, formed from cum (“together”) and munus (“gift, task, obligation”), literally “to make common, to share something with someone”.

As an interpersonal form of exchange, communication is divided into different types of communication: verbal communication, non-verbal communication and visual communication. For certain specific needs, as a first inclusive choice, augmentative communication (or augmentative and alternative) is also used. In many contexts, the transmission of a message is used as a synonym or direct synonym for sharing.

In a business context, this process spans marketing, corporate communication and online digital communication; it contributes to building branding and also makes a unique selling proposition visible to the market when the company has a concrete reason to be chosen, thanks to effective communication.

The etymological root is already a definition: communication is not a one-way act of transmission but a two-way act of sharing. One does not “communicate to” someone: one “communicates with” someone, in the sense that the process is not complete until the meaning has been received, interpreted and to some extent shared by the other party. A message transmitted but not received is not communication: it is noise. A message received but interpreted in the opposite way to the sender’s intention is failed communication, and its consequences, in a business setting, can be as costly as total silence.

The economic scale of communication in 2026 is unprecedented. Global advertising spend will exceed 1,000 billion dollars for the first time in 2026, growing faster than world GDP (dentsu Global Ad Spend Forecasts, cited by Bitmat, December 2025). Global digital advertising spend will reach 781 billion dollars in 2026, equal to 68.7% of all global advertising investment (Affinco / IAB, 2026). Total global spend on advertising and marketing had already reached 1.92 trillion dollars in 2025 (Affinco, 2026). These figures do not merely describe a market: they describe the extent to which organisations worldwide have understood that communication is not an operating cost but an investment in building perceived value, which is the most decisive variable in purchasing choices in markets saturated with comparable alternatives.

1. The history of communication: six milestones from Aristotle to artificial intelligence

Antiquity: rhetoric as the first theory of communication

In the 4th century BC, Aristotle wrote the Rhetoric: the first systematic treatise on the art of persuasive communication. For Aristotle, effective communication rests on three pillars: ethos (the speaker’s credibility), pathos (the ability to stir emotion in the listener) and logos (the soundness of the logical argument). The Aristotelian triad anticipates by two thousand four hundred years the contemporary framework of brand communication: credibility (who you are), emotion (what you make people feel), argument (why choosing you makes sense). It is no coincidence that these three elements remain at the heart of any contemporary course in copywriting, branding or strategic communication. Cicero, in 1st-century BC Rome, would further formalise the art of persuasion as a political and professional skill, setting out the five stages of the rhetorical process: inventio, dispositio, elocutio, memoria, actio.

The printing revolution: mass communication

1450 is the year that divides the history of communication into a before and an after: Johannes Gutenberg’s movable-type printing press turned communication from an individual act into a mass phenomenon. Before Gutenberg, a manuscript required months of work and could reach dozens of readers. Afterwards, a printed edition required hours and could reach thousands of people in identical form. Standardisation of the message, separation between the producer and the recipient of content, the ability to reach geographically dispersed audiences: these are all characteristics born with printing that foreshadow the logic of modern advertising. The first recognisable form of advertising emerged in this context: advertising “billboards” appeared in European cities as early as the 16th century, on the walls and posts of the public square.

19th and 20th centuries: the media and the birth of industrial communication

The telegraph (1837), the telephone (1876), radio (1895), cinema (1895), television (1927): each new medium of the 19th and 20th centuries widens the scope of communication and redefines the relationship between sender and recipient. Modern advertising was born in this context: the first American advertising agencies appeared in the 1840s, and the first national advertising campaign (for Ivory Soap by Procter & Gamble) dates from 1882. In 1948, Claude Shannon and Warren Weaver published “A Mathematical Theory of Communication”: the first formal model of the communication process, which breaks communication down into six elements, sender, encoder, channel, decoder, receiver and noise, and establishes the principles of information as a scientific field. It is the model that formalises the distinction between effective and distorted communication, introducing the concept of “noise” as any interference that compromises the fidelity of transmission.

The 1960s: Jakobson and communication as function

Roman Jakobson, the Russian linguist, extended the Shannon-Weaver model in 1960 by introducing the functions of language: every communicative act can be analysed according to the prevailing function it pursues. The referential function (informing), the emotive function (expressing the sender’s state), the conative function (influencing the addressee), the phatic function (keeping the channel open), the metalingual function (talking about the code) and the poetic function (attention to the form of the message). For corporate communication, Jakobson’s model is still a powerful analytical tool: every press release, every social media post, every advertising campaign can be analysed in terms of which function it favours and whether that function is consistent with the brand’s strategic objective.

The 1990s and 2000s: the digital revolution and interactive communication

The internet turns communication from a linear process (a sender transmits to a recipient) into a networked process (everyone can communicate with everyone, simultaneously, without intermediaries). Web 2.0, with blogs, forums, social networks and user-generated content platforms, shifts control of communication from the company to the market: for the first time, consumers can respond publicly to corporate communications as easily as companies produce them. This structural change forces companies to move from broadcast communication (one speaking to many) to dialogic communication (many speaking with many), completely redefining the role of marketing and corporate communication.

2020-2026: the age of AI and the attention crisis

Generative artificial intelligence, available at mass scale since the arrival of ChatGPT in 2022, has driven the marginal cost of producing communication content down to zero. A text, an image, a video: any format can be produced in seconds at almost zero marginal cost. The direct consequence is an unprecedented saturation of the communication space: the average consumer is exposed to thousands of messages a day and consciously remembers only a fraction of them. In this context, the differentiating value lies not in the quantity of communication produced, but in the quality of the attention captured and the depth of the relationship built over time. As the Wayap report on 2026 marketing trends notes: “Corporate communication can no longer be mere ‘promotion’; it must build relationships and communities.”

2. The three fundamental models of communication

The circular model of Watzlawick and colleagues, formalised in Pragmatics of Human Communication (1967), makes the most relevant contribution to contemporary corporate communication: every behaviour of an organisation, silence included, is communication. A brand that does not respond to negative reviews on Google is communicating something. A company without a defined tone of voice is communicating inconsistency. A management team that proclaims values in official statements and contradicts them in internal conduct is communicating hypocrisy. Brand communication is not only what is said: it is what is done, what is left unsaid and the way anyone who interacts with the organisation is treated.

3. The three forms of business communication: marketing, corporate and brand

In Italian management practice, the terms “marketing communication”, “corporate communication” and “brand communication” are often used interchangeably. They are not synonyms. They have different origins, different objectives, different audiences and are measured against different KPIs.

Marketing communication

Marketing communication, or marketing communication, covers every activity that supports the sales process: advertising, promotions, direct marketing, content marketing, email marketing, SEO and social campaigns. Its primary objective is conversion: turning a prospect into a buyer. It is measured with performance metrics: impressions, clicks, conversions, ROAS, CAC. It is the form of communication with the shortest time horizon and the most directly measurable ROI. Integrating marketing communication into a coherent system that works across all channels, with messages aligned with the brand’s identity, is the central challenge of integrated strategic marketing.

Corporate communication

Corporate communication concerns the organisation’s relationship with its institutional stakeholders: media, investors, institutions, local communities and employees. It includes public relations, press releases, investor relations, internal communication, sustainability reporting and crisis communication. Its primary objective is institutional reputation: building and maintaining the organisation’s credibility as a responsible and reliable actor. It is measured with reputation metrics: share of voice in the media, internal NPS, investor confidence and qualified editorial coverage. Corporate communication has become even more strategic in 2026, at a time when the Edelman Trust Barometer shows that business is one of the few sectors still perceived as relatively trustworthy (a score of 64 out of 100) amid widespread institutional distrust.

Brand communication

Brand communication is the most strategic and long-term form: it concerns building and managing the brand’s perceived identity in the minds of its target audience. It does not sell (as marketing communication does) and it does not manage institutional relationships (as corporate communication does): over time it builds preference, trust and an emotional bond between the brand and people. It is measured with brand equity metrics: brand awareness, brand consideration, brand preference, external Net Promoter Score, brand value. It is the form of communication with the longest time horizon and the ROI hardest to attribute to individual campaigns, but with the greatest impact on the company’s overall value in the long term. Brand governance is the system that ensures the consistency of brand communication over time, through team changes, crises and market shifts.

4. Communication market data in 2026

The communications market in 2026 is the largest in human history, and it continues to grow faster than the real economy. Global advertising spend will exceed 1,000 billion dollars for the first time in 2026, growing faster than world GDP (dentsu Global Ad Spend Forecasts, Bitmat, December 2025). Specifically, digital advertising is worth 781 billion dollars in 2026, equal to 68.7% of total global advertising investment (Affinco / IAB, 2026). The creator economy, that is, communication delivered through content creators, was already worth 37 billion dollars in 2025, with growth to 44 billion forecast for 2026 (IAB / PwC, cited by Youmark, April 2026).

In Italy, the Out-of-Home market reached €766 million in 2025, growing by +8%, with €838 million expected in 2026 (+9%): the only traditional medium in structural growth, while average growth across other traditional media stalled at +0.4% (Wayap, April 2026). Digital is driving growth in every market: retail media (+14.1%), online video (+11.5%) and social advertising (+11.4%) are the formats with the highest CAGR in 2026 (dentsu, 2025).

The paradox of 2026 is that in a communication market growing exponentially, consumer attention is the scarcest resource. The volume of messages produced is growing faster than the human capacity to process them: the result is communication inflation, which erodes the value of each individual message and raises the premium for those brands able to build communication that is genuinely differentiating, consistent and memorable over time.

5. Communication and brand: the relationship that creates value

Communication without brand identity produces noise. Brand identity without communication remains implicit and creates no market value. Value is produced at the intersection: communication that expresses a solid identity, consistent over time, relevant to its audience and verifiable in the organisation’s actual behaviour. This is the system that Bliss Agency builds with its clients: not individual communication campaigns, but integrated systems in which every message reinforces the brand identity and every expression of the brand is consistent with the documented identity.

Effective brand communication has four characteristics that set it apart from generic communication: it is consistent over time and across channels; it is authentic, in that it reflects something real in the identity of the organisation; it is relevant to its target audience, responding to real needs and values; and it is verifiable, with evidence backing its claims rather than mere slogans. The fourth characteristic, verifiability, is the one that has gained the most importance in 2026: in a market where any claim can be checked instantly through reviews, social media and AI Search, the gap between what you say and what you do is a reputational debt accruing compound interest.

6. Real examples: when communication delivers verifiable results

Dove: one line of communication that has lasted seventy years

The Dove case is the most frequently cited reference on the longevity of brand communication: the positioning David Ogilvy built in 1957 (“the soap that doesn’t dry your skin, because it is one-quarter moisturising cream”) has remained essentially unchanged for almost seventy years. Not because Dove has not invested in new campaigns, but because every new campaign has built on the same identity foundation, adding cultural relevance (the 2004 “Real Beauty” campaign is one of the most studied cases of brand communication in the world) without ever abandoning the original promise. The result is a brand with exceptional brand equity in a category, skincare, where the technological barriers between competing products are almost non-existent.

Bliss Agency’s integrated communication work

At Bliss Agency, communication is never treated as an activity separate from brand identity. The Doreca case, a HO.RE.CA. beverage distributor, documents how integrated communication built on a coherent brand identity delivers results across all channels simultaneously: 2.5 million TikTok views, +471% on Instagram, a Google Ads CTR of 13.36% on 51,599 clicks. These are not separate results from different campaigns: they are the outcome of a unified communication system that speaks with the same voice across channels with entirely different formats. The Profumum Roma case, a luxury heritage perfume house, shows how well-positioned brand communication reduces the cost of advertising: a ROAS of 17.1 on Google Ads ecommerce is not a campaign management achievement; it is the consequence of premium positioning communicated so effectively that the target audience was actively searching for the brand, lowering the cost of each conversion. Bliss Agency has a dedicated page on corporate communication strategy with practical insights on the subject. For details on the case studies: Bliss Agency case studies.

7. The 5 Ws of corporate communication

• • Who: Any organisation that interacts with external or internal audiences, which means every organisation without exception. Watzlawick’s principle is incontrovertible: one cannot not communicate. The choice is not between communicating and not communicating, but between communicating in a deliberate, structured way or in a random, inconsistent way, with the consequences that follow for how the market perceives you.

• • What: The process through which meanings are shared between sender and recipient by means of shared signs, with the aim of producing a verifiable response. In a business context, communication takes three forms: marketing communication (objective: conversion), corporate communication (objective: institutional reputation) and brand communication (objective: long-term preference).

• • When: Effective communication requires strategic planning, not reaction to events. The brands with the strongest communication performance in 2026 are those that defined their communication plan before crises, before launches and before market shifts, not those that react in real time without an established direction.

• • Where: Across every touchpoint where the organisation meets its audiences: paid media (advertising), owned media (website, social, newsletter), earned media (editorial coverage, reviews, word of mouth), shared media (community-generated content). Integrated communication covers all four levels with consistency of message and identity.

• • Why: Because global advertising spend exceeds 1,000 billion dollars in 2026, signalling that organisations worldwide have already understood that communication is an investment, not a cost. And because the market is so saturated with messages that only those who build genuinely differentiating, consistent and verifiable communication manage to win and hold attention over the long term.

8. 2026 trends: how corporate communication is evolving

AI in communication: an accelerator of quantity, not quality

Generative artificial intelligence has transformed how communication content is produced: a text, an image or a video can be created in seconds at almost zero marginal cost. This has lowered the barrier to entry for mass communication, but it has also lowered the average level of perceived quality. The paradox of 2026 is that AI has made mass communication easier and authentic communication rarer, and therefore more valuable. Organisations that use AI to amplify a solid, documented identity gain a real advantage of scale. Those that use AI to fill the void of a non-existent identity produce content indistinguishable from the market average, at lower cost but with equally mediocre results. Corallo AI, the AI division of Bliss Agency, has built its methodology on this principle: first build the brand’s identity and knowledge base, then use AI to amplify it consistently and at scale.

GEO Strategy: communicating to be found by AI systems

In 2026, communication has acquired a new dimension: being found by human users on Google is no longer enough; brands must be cited by AI systems such as ChatGPT, Perplexity and Google AI Overview. Generative Engine Optimization, which Bliss Agency covers through its GEO Strategy, is the process of optimising the brand’s presence in the answers given by AI engines. It does not replace traditional SEO: it extends it into a dimension where structured, authoritative and verifiable communication has a structural advantage over generic content, regardless of the volume produced.

Communication as community building

The most significant trend identified by the leading 2026 marketing reports is the shift from communication as “promotion” to communication as “building relationships and communities” (Wayap, 2026). The most effective brands of 2026 do not try to reach passive audiences with broadcast messages: they seek to build active communities of people who share values, interests and a relationship with the brand that goes beyond the commercial transaction. This radically changes the measure of communication success: not the number of impressions, but the depth of the relationship with the audience; not maximum reach, but the loyalty and advocacy of the most engaged segments. It is a communication model that requires long-term consistency, verifiable authenticity and a brand identity solid enough to attract the right people and keep the wrong ones at a distance, two functions that good brand positioning performs automatically.
