I think you will see a point where the traditional model of advertising on TV or advertising online will go, and advertisers will cover one programme, no matter what platform it's being broadcast on. You'll see the same ads whether you are watching it on your TV, your computer or your phone.
I think a lot of people may have a unique insight or some idea that they feel could be a great solution for a particular problem, but for some reason never have a chance to try or never have the courage or maybe the self-doubt. Really, it's best just to remain naive and continue to work on things and see if people have the same problems.
