Every message is shaped by the mechanics of media. Whether it’s a tweet, a TikTok video, a news article, or a movie, the characteristics of the medium determine how it’s made, how it’s consumed, and whether it spreads. If you understand the mechanics of media, you can more effectively communicate in a wide variety of mediums, and protect yourself from being manipulated by media. The message is the mechanics of media As media theorist Marshall McLuhan said, “The medium is the message.” In Understanding Media, he wrote: The medium is the message. This is merely to say that the personal and social consequences of any medium...results from the new scale that is introduced into our affairs.... In other words, it’s not the content of the medium we should be worried about, but the way the characteristics of that medium determine its content – the mechanics of media. The five characteristics of media I propose that there are five characteristics present in any medium, which determine these mechanics. These characteristics affect the creation, consumption, and distribution of media. (In other words, what message is delivered, how that message is received, and whether or not that message spreads.) Those five characteristics are: Incentive Sensory Physical Social Psychological The mechanics of media are so complex, these characteristics naturally interact with one another. I’ll give a brief introduction of each, then show how these characteristics work in the popular mediums of podcasts, Twitter, and TikTok. 1. Incentive The Incentive characteristics of a medium are sources of motivation, whether money or otherwise, that shape the creation, consumption, and distribution of messages in that medium. The creator of a piece of media is motivated by various incentives, such as money and relationships. Whether or not someone is able to consume a piece of media depends upon whether its affordable or otherwise accessible. Whether or not a piece of media spreads depends upon whether incentives are aligned for the distribution platform to allow it to spread. So, a journalist may be motivated to write a story that gets page views, because that’s how they’re paid. That’s how they’re paid, because the newspaper doesn’t have paying subscribers and thus relies upon ad revenue. The stories with click-bait headlines spread and get more page views because they increase engagement for the social media platform they’re shared on, which increases the social media platform’s ad revenue. 2. Sensory The Sensory characteristics of a medium are the ways in which the medium engages senses such as sight, hearing, and touch. Marshall McLuhan wrote about how so-called “sense ratios” were engaged by a medium. Sensory characteristics primarily affect the consumption of the medium, but those effects overlap with creation and distribution. Written content, for example, can be absorbed at a reader’s own pace. As Neil Postman pointed out in Amusing Ourselves to Death, the written word is especially well-suited to careful review and comparison, which makes it easier to convey the truth. Audio content can be replayed to be reviewed, but it’s more work than simply moving your eyes back over the content. 3. Physical The Physical characteristics of a medium are the ways in which the medium engages the body. The subtitle of Marshall McLuhan’s Understanding Media is Extensions of Man. As a medium extends our abilities, it also removes or “amputates” abilities. When you listen to a podcast, your entire body is free to do other things. You may be cooking, showering, or fighting your way to the exit of a crowded subway car. So, audio with dense content may not be absorbed as well as if the same content were printed in a paper book – which can still be read on a subway car, but not likely while walking. Podcasts became distributed more widely as they became easier to download on smartphones, which people physically carry around. 4. Social The Social char
