Adverts:
- a good reason to swap through the channels and look if there is something interesting somewhere.
- if swap shows that ad-time is everywhere => a very good reason to switch off the TV and do something else
- might be a very good source for aliens observing our societies to quickly conclude that we are no intelligent species
- shows the decadence and fall for consumer products, our "Zeitgeist" => time spirit, fashion
- Sims in RL, so you might not even need to buy the game
- cheap way to build up illusions that your life is perfect if you => buy the right soap, eat the right stuff, wash your hair with the right foam, booze the right stuff, smell the freedom of smoke.
- helps to press people into little boxes and makes them lose individuality, as they become living ads for all products that promise more than they ever plan to achieve. Therefore they are a helpful tool to be manipulated.
- keeps people busy with earning money and yearning for all these products
- are sometimes quite funny

So? Ads are very important, as they help you to spend your money and keep you from thinking what you are really lacking. Conveníent, hm?
