IT'S HARDLY stop-the-presses news that we love old TV shows. There probably hasn't been a day in three decades or more that didn't see some outlet showing reruns of such classic fare as "I Love Lucy" or "M*A*S*H."

But for fans of classic TV, these are high times indeed, with the explosion of new channels specializing in vintage programs from the 1950s through the '80s. And we're not just talking the pop culture touchstones, either. For every "Gilligan's Island" or "The Brady Bunch," there is a far more esoteric but no less-entertaining program to be found, from the cerebral 1960s drama "Route 66" to the "Twilight Zone"-ish "One Step Beyond."

Technology and economics are the twin engines propelling this rise in nostalgic programming. The recent digital transformation of local TV has provided stations with sub-channels that represent added revenue sources for outlets like NBC10, whose Cozi TV affiliate is on channel 10.2, and PHL17, which carries Antenna TV on channel 17.2.

On the number-crunching front, old TV shows are a relatively low-cost investment, especially the more obscure titles, according to David Bianculli, TV critic for NPR's Philly-based "Fresh Air" program and creator of TVWorthwatching.com.

More to the point, noted Bianculli, there is a sizable audience that loves nostalgic shows.

"Viewing by young people [of vintage programs] isn't what it was a generation ago," said Bianculli, who also teaches TV and film at Rowan University. "They go straight to their own channels - Disney Channel, Nickelodeon, MTV, Comedy Central. They don't even have the exposure to these sorts of shows. So what's happened is that cable television and local television stations have begun to fill in this gap, mostly with older viewers."

While Bianculli is thrilled that such programming is so widespread, he did offer a caveat: "A lot of these channels, though they're showing [series] you can't see elsewhere, they aren't treating them with the respect they deserve. They're speeding them up, they're cutting them up. And that's really irritating to me.

"In my dream TV world, there would be a 'Masterpiece Theater' of old television, where [shows] would be presented in context at regular speed without editing."

So, you've been forewarned; but if you're still yearning for vintage TV, here are some places to find it.
