An Internet without marketing advertisements. Is it possible?

Remember back in the 70's and 80's before cable TV? We only had channels 3,6, and 7. We loved TV but couldn't stand the commercials every 5 minutes. The internet has turned into one big TV commercial. Websites are now 10% content and 90% ads. It is so sad that we let this get out of control. Don't get me started on social networking and how they exist to be the big TV commercial just to make boatloads of cash.
