The first episode of "Mister Rogers' Neighborhood" was broadcast on PBS on February 19, 1968. Fifty years later, the program is still being shown on public television stations, to the delight of both children and adults. Though he passed away in 2003, Fred Rogers' philosophy continues to influence children's television today.

Much of the current PBS stuff is available online, particularly kids programming. For example, Daniel Tiger's Neighborhood (essentially a Mr Rogers animated spinoff) is available via streaming on PBS Kids and Amazon Prime (possibly others as well). I've also pulled it off of torrent sites, since I don't see the point of streaming the same episode 6 times when the kids want to watch it over and over again.
Many old shows had problems with coming to DVD. For example, The Muppet Show, Fraggle Rock and The Wonder Years all got hung up in copyright stuff for ages. Even Seinfeld and ER had to wait 10 or so years agter the original airdates before you could buy them.
