Are deaf people nocturnal?

Q: How comes it seems that a signer (person who does sign language) only seems to come on the tv late at night? Do deaf people stay up all day and wait till the early hours of the morning to be able to watch the news and other programs? This is a serious question, I just don't understand why there are only people doing sign language on tv after around 1am...

A: They're just deaf. They aren't vampires. ^..^
