You are right. The History Channel has become this. To compensate, they have now developed a History 2 Channel which has actual History on it. However, I don't know if it's accessible to everyone with cable. Good question you've asked. It's all about money. People love those reality shows and it makes good money for the channel.
They're all doing that ..History,Nat Geo and Discovery has been nothin but reality shows forever:.....kinda like MTV now that I think about it!! Gotta watch The Science Channel an Nat Geo Wild...H2 Is ok
