Advertisement on TV

I always see on TV different types of advertisement and some of them are very annoying. I don’t know why they have commercials that are not really informative. What I hate the most is that they keep on showing the same one over and over again. But there are some advertisement that are informative like mesothelioma . This commercial helps you to know all about what it is and what it does. And I don’t really mind watching it over and over again because I think its really helpful.
