The internet didn’t start as a business. Not really. But by 1997, the vibe shifted. Venture capital poured in. Billions of it. Thousands of new websites popped up overnight, splitting into two distinct tribes.
First, you had e-commerce sites. These guys sold stuff. Shoes, books, gadgets. Their model was simple: sell a product, keep the margin. Just like a brick-and-mortar store, but with better lighting and no salespeople hovering over you.
Then there were content sites. These places didn’t sell widgets. They sold words, pictures, and eventually video. To pay the bills, they needed advertisers. Think newspapers. Think radio. The money came from eyeballs, not checkouts.
The Golden Age Of The 728×90 Banner
Back in the day, “advertising” meant one thing: banner ads. You know the strip at the top of every page. Usually 728 by 90 pixels. It was everywhere.
In 1998, this was gold.
Popular sites like Yahoo could charge $30, $50, or even $100 per thousand impressions (CPM). That sounds high now, but it made sense to investors. The math was seductive. If you could drive 100 million page impressions a month, you were looking at $3 million in ad revenue. Easy money. The logic drove the venture capital boom. Build traffic, slap on a banner, get rich.
But where did those price tags come from?
Magazines. Specifically, the cost of a full-page color ad in a print magazine. The internet copied the model and pasted it onto a web browser. It was a direct translation of print economics to digital space.
Why Banner Ad Rates Plummeted
Advertisers eventually realized something awkward.
Banner ads didn’t work like magazine ads. They weren’t even close to the impact of a 30-second TV spot. People ignored them. They scrolled past. The medium was noisy, the attention span was short, and the conversion rates were abysmal.
At the same time, supply exploded.
Thousands of sites suddenly had millions of impressions to sell. Companies like DoubleClick stepped in, aggregating this massive pool of banner inventory. They bundled it up. They created a marketplace.
Economics 101: supply meets demand.
When everyone has inventory and no one is buying, prices drop. The glut of ad space caused rates to plummet. The $100 CPM fantasy evaporated. The easy money dried up.
So what actually determines the rate you pay for a banner ad today? It’s not just about how many people see it. It’s about who they are, what they’re doing, and where the ad lives.
