why do movie starts want to depent on TV and look cheap?

Well I guess that's how it really works! Celebrities have to promote their movies on TV in order for the people to be aware and updated. :)

I feel that the way stars present themselves, and the shows they choose, are more important. After all, they are people doing a job that requires they be noticed to be stars, and TV is more viewed. Also, the quality of television shows through the 2000s has become much more in-depth, like reading a good book. Not all of it, but a good number of shows. I don't feel like it's a step down for actors (even stars) when they are truly portraying the characters and doing justice to a good show... when you don't quite remember that you're watching someone famous.

The world is a changing place. People used to only be able to go to the cinema to watch movies. They even posted news stories along side the movies. Then as years have passed cable has gotten bigger and better. Even the smallest cable packages typically offer close to 100 channels. People have less of a reason to go to the movies. Also instead of spending money on movie tickets many are watching pirated films online. Since the popularity of television has been on the rise and less people are visiting the cinema actors are put in an awkward position. I agree that movie actors should maintain a certain class. It looks cheap to me when they show up on TV shows however since ticket sales are down they're just doing whatever they can to promote themselves. I think its a shame it has come to this but I guess the cinema is just not what it used to be.

Movies need promotion. Even the best movies have to promote themselves, otherwise, no one will know they exist. And TV has much more viewers, so it gets more attention and attracts more viewers.
