Why are there ads? Why isnt it letting me watch shows?

I love Cartoon Network but I dont understand why there are ads. Please, no one wants to watch ads instead of watching their favorite shows. Anyways, mine isnt letting me watch any of the videos anymore. I go in, pick a show, and then watch the stupid 35 second ads, then the video loads, and say, oops there was a mistake. Try again, so I try a million times and it keeps showing that dumb oops message.....
