Keep in mind that all three networks are pretty agressive in cable. CBS owns MTV and Comedy Central. ABC is owned by Disney, which owns the Disney Channel. Fox owns FX. So they all have their hands in pay TV. Although NBC has the biggest share. They use Bravo for second airings of current network shows.
Corporate-wise, NBC-Universal is broken into competing divisions, so it is to the NBC Chairman's advantage to beat the cable shows, if he is able. It's not much different than having the cable channels owned by another company. If you want a bonus, you need to beat the other division. But NBC was in last place before Leno.
If you watched the Screen Actors Guild awards, there were a whole lot of cable shows nominated and winning. That's where companies have bigger program budgets, because they have two incomes: Advertising and subscriber fees. That is really where the future of "quality TV" is heading.
Disney also owns ABC Family, which now produces original programming. CBS also owns premium cable channel Showtime, which produces a LOT of original programming. During the writer's strike last year, CBS re-broadcast
Dexter from Showtime, though I imagine some editing for content was necessary.
CBS is a little different in that Viacom actually owned Showtime, MTV, VH1, and Nickelodeon
before they bought CBS. Viacom started (or purchased) these cable channels when they were still a cable TV provider. I don't recall if they purchased Comedy Central before or after they bought CBS.
So even though they have spun CBS back off into a separate corporate entity: in a real sense, Summer Redstone and his company were into cable first.
None of these media corporations wants to limit programming development to only their broadcast divisions. It makes perfect sense to produce some shows for cable - there's less pressure to get big ratings, and less pressure to produce 20+ shows every year. And when those shows are a success, they can strip them for years in reruns, syndicate them to local broadcast stations, and sell them on DVD.
Just look at the success of
Monk, and the "synergy" it created.
