JetBlue is of course famous for their DirecTV on the back of every seat:
However, as nyanko pointed out recently, it would be nice if one of the channels was a program guide! They do provide an online version on their website, which you can print and bring with you - if you remember to do that before your flight...Unfortunately even that wouldn't have helped with the problem my last flight encountered - many of the channels looked like this through most of the flight, rendering them completely useless:

Maybe I'll have better luck this time :)
