Once upon a time, each cable network had its own distinct identity and its own reason for being. Roughly 10-15 years ago, they started to slowly meld into a little bit of the same thing on each network, with just a hint of what previously made each network unique.
For example, "Sci Fi" is now "SyFy" to downplay its previous focus on science fiction. "The Learning Channel" is now "TLC," and its programming is now lacking in anything that could be termed "learning." "ABC Family" keeps the word "Family" in its name because it is contractually obligated to do so, but that's where anything "Family" begins and ends. Fox News and MSNBC are no longer news organizations, but "analysis and opinion" networks, although only MSNBC openly states that. Basically, it's only ESPN that hasn't changed its focus over the decades.
