The best way to determine whether or not a show is popular is by the number of people who watch the show. If more people watch the O'Reilly Report than any other news show, then the O'Reilly Report, is, in the court of public opinion, the most popular news show on television. Ultimately, it isn't a matter of whether the show has sufficient merit to be the most popular -- the true, and only accurate, indicator of popularity is the number of people watching the program. If more people are watching it then any other news program, then the public has decided that the O'Reilly Report deserves to be the most popular news show on TV.
Whatever news report gets the most viewers deserves to be the most popular news show on television. Whether or not you agree with what it is reporting is a different story. Whether you like O'Reilly or not you can not take away the fact that more people tune into his program than any other news program.
I think all news shows deserve to be popular because people put a lot of effort and sweat into becoming a great company and news show to deliver the people of the country with accurate and interesting information about what is going on in the world today and what we should know.
No, O'Reilly does not deserve to be the most popular news show on television, because O'Reilly is not that smart. He is also loud and overbearing. Of course, he is a big improvement from the ones on MSNBC, but there is nothing so special about his show that would make it the most popular show on television.
The O'Reilly Report does not deserve to be the most popular news show on television. I am fond of CNN but I rarely watch the O'Reilly Report. It is not bad but I just do not think that it is the most popular of the news shows that are on.
