It's true — but advertising has two sides. You can of course be running a campaign that you're hoping for immediate ROI on, like a flash sale. In that case, you really want clicks and some sort of immediate indicator that the campaign is working, like conversions.
But sometimes as a business owner you're also campaigning for visibility / mindshare. At the minimum you want to distribute a message and let people know you exist. That's why people still buy billboards. It's a type of advertising that will probably never go away - especially because it's relatively low cost to implement for all sides - just need a designer to create the ad and you're good to go.
It doesn't seem like the most dependable business model but it's pretty timeless even in the digital age. The advertiser has an ego and instinct and is ultimately going to buy what they feel is going to work for their business.
