Last night I watched this really cool movie on the SciFi channel where a very attractive woman was exposed to a experimental bio-chemical weapon and acquired supernatural powers which she used to blow-up lots of things and kill several bad-guys. It was entertaining at a time when I had absolutely nothing better to do and wasn't sleepy.
If it wasn't for Progressive Insurance, Procter-&-Gamble, Kraft Foods and a few others, the producers of that "made for TV" movie would have had no incentive to create it and there would be no SciFi channel. Have you ever watched anything on PBS? That's what TV would look like without commercial advertisers. Do you remember what the typical Web page looked like in 1990? That's what they would still look like without the contribution of commercial advertisers. I wouldn't buy some miracle wrinkle remover cream, but I do buy countless useful products. You have to rely on your common sense to determine what to buy or not. This has nothing to do with the Internet; you have to do that at the store too.
Television has the ability to appeal to your senses of hearing and vision with very high-quality, life-like animation. Internet advertising is basically restricted to printed words and crude animation. It's much harder to create effective advertising for the Internet, but the same rules still apply. Google is NOT a non-profit organization. If it weren't for "paid" advertisers, they would have no incentive to purchase millions of dollars in technology and employ 1000's of people world-wide.
If you want to help the Internet evolve, try buying something besides an ad-blocker. Do your banking and make purchases using your debit/credit card and let UPS bring it to your door instead of driving 20 minutes to get there and standing in line for 20 minutes to checkout. With your help, we can turn all Wal-Marts into indoor ice-skating rinks.
