Personally, I'd like to see decades channels for classic TV.
A 50s channel, for shows like I Love Lucy, The Honeymooners, and any other shows from that decade (assuming they still exist).
A 60s channel, for shows like Gilligan's Island, I Dream of Jeannie, Bewitched, Andy Griffith, etc.
A 70s channel, for shows like All in the Family, The Bionic Woman, Charlie's Angels, etc.
An 80s channel, for shows like Small Wonder, Alf, Facts of Life, 21 Jump Street, Knight Rider, etc.
A 90s channel, for shows like 3rd Rock from the Sun, Veronica's Closet, Dr. Quinn Medicine Woman, Honey, I Shrunk the Kids, etc. (any of these old enough to be classics, yet?)
A 2000s channel, for shows like The Bernie Mac Show, Malcolm in the Middle, etc. (again, same question as that about 90s shows)
As for shows that straddled two decades (for example, Full House, which premiered in 1987 and ended in 1995), the episodes from the 80s and the 90s could be on the appropriate decade's channel.
Thoughts?
