It would be a mistake to replace formal news segments with less formal comedic ones.A sense of Seriousness needs to remain in order to engender a sense of trust in the audience.The best way to keep the audience attention is to mix serious segments with more comedic ones that make audience laugh,
Those traditional news segments are led by long-winded and pretentious analysts because that is the best way to analyze the situation. Bill Maher still reports on certain things but does not allow the viewer the chance to form their own opinion based on the facts surrounding an incident. Wolf Blitzer will provide the relevant structure of the environment and the actions taken by the players and analyze these things with a more objective point of view. Bill Maher will only talk about the points that are funny or exciting.
You can't just throw people where they don't belong. There is a market for each and every type of person. If you put Bill Maher where he doesn't belong, how is he going to succeed? I doubt Bill Maher ranks high amongst the elderly and other certain groups of people. He has his place as does Wolf.
I think that more traditional news segments, like those hosted by Wolf Blitzer, still have a place in television. Shows like it are about reporting events and issues in a serious and factual manner. Bill Maher is a comedian who hosts a show with a political concept. Both type of shows have a market.
No, traditional news segments such as those hosted by Wolf Blitzer, should not be replaced by less formal and stuffy segments hosted by comedians like Bill Maher, because there is enough room on television for whatever people want to watch. People who are waiting in the airport probably want to watch CNN. At 3 AM in the bar, they probably want to watch comedy. There is a good balance right now.
