It might not be a bubble, but there&#x27;s an oversupply of advertising space. TV, radio and print ads have traditionally been expensive due to the limited supply. You can only have so many ads in an hour of television programming.<p>Now we have a hundred TV channels, a massive amount of online content, all attempting to attract ads buyers. As a result the price has gone down. The oversupply also opens up the marked for targeted ads and companies that works as brokers. They need to get paid to, so they skim of a few percent, leaving even less to the sells of the ad space.<p>In the end I don&#x27;t think that selling advertising space is sustainable for all but the very biggest content providers. The rest will have to have to start finding alternative sources of revenue, or simple charge for they content. I also believe this will leave us with better and more diverse content.
