There are early shows that would benefit to having highlight reels or selected episodes:
Mr. Roger's Neighborhood
Gilligan's Island (simply because of the silliness of the situation)
The Brady Bunch
Scooby Doo (which has a life of it's own)
The Honeymooners (hard to find, tho)
I Love Lucy
Star Trek, it seems, will never die, and The Next Generation is worthy after the cringy first season.
Then there are shows that I think will be interesting and watchable as a whole, or at least a number of seasons for a long time:
MASH
The West Wing
Possibly Hill Street Blues
I think certain TV shows will have a long life. They have their place in visual entertainment and have an integrated history with, but different from, movies and deserves their own historic place. The current "golden age" will certainly have permanent fixtures. The Wire is made up of five long, excellent movies. I won't give up on it.
