Advertising is not the major form of revenue on every form of content. Not on TV-formats like Netflix, for example, even if it has started there as well. Why is it so widespread? Because advertising is relatively simple to explain, to add to a website and to sell. Also, try selling subscriptions to a news website 20 years ago… Does it make sense to sell ads? Not everywhere. Not on Ebay, for example — they started some 20+ years ago, and it was dumb and painful to see. I have no idea if Ebay still sell banner ads or not — I really could not use the web without Ublock Origin, sorry. Do ads actually work? For Google and Facebook, who sell a huge percentage of online advertising, they sure do. Other companies have had a much harder time — just look at the company formerly named Twitter. Do they work for companies who buy ads? IMHO they do (sometimes) for startups or small firms that are testing out whatever it is they are trying to do or sell. They usually don’t for large companies, like giants selling mainstream products. These people should stick to teevee, but some of their marketing people want to try something new, or change jobs, or acquire experience in a new field (on company money) and so they unwisely waste tons of money. If you disagree, please name a few major brands that were created thanks to Internet ads. No, Amazon, Google, Facebook, Netflix etc were not.
