That will be number 57, according to the Observer, as Time Warner Cable follows up on last months additions with Fox News HD on channel 720. Jumping on the free HD tier just in time for the run up to the election, the high definition simulcast of standard Fox News coverage should please all those tuning in. It may have taken time for Buffalo to catch up on HD, but it looks like the streak will go on. [Disclosure: Engadget is part of the Time Warner family]
