the first banner ad

AT&T's 'Have you ever clicked your mouse right here? You will.' on HotWired, October 27, 1994 - the ad that founded the web's business model.
There was no single first: HotWired launched with roughly a dozen 468 by 60 pixel banners from AT&T, Volvo, Club Med and others, and GNN had sold a clickable ad the year before. But AT&T's rainbow-lettered dare became THE one, with its creator reporting that around 44 percent of viewers clicked, a rate the industry never saw again. Everything the modern web gives away for free is descended from that afternoon.
The first banner advertisement appeared in 1994 on HotWired, and it worked extraordinarily well by any modern standard, reportedly with a click-through rate that would now be considered impossible. Its novelty was the entire mechanism.
What it began is more consequential than the advertisement. Once display advertising funded content, the incentive became measuring who saw what, which produced tracking, then cross-site tracking, then the profiling infrastructure that most privacy regulation now exists to constrain. That chain runs directly from a single banner to the modern surveillance economy, and no step in it was a conspiracy: each was a rational response to advertisers wanting to know what they were buying.
The counterfactual is what makes it worth teaching. Advertising funded a web that was otherwise going to be either paywalled or hobbyist, and the free access that resulted is genuinely valuable. The costs arrived later and are borne diffusely, which is the standard shape of an externality. Anyone arguing about the economics of the web today is arguing about consequences that were set in motion by an experiment nobody expected to work.
