You know, dramas are much more expensive to do than say a comedy, so any kind of deficit like that is picked up on when it comes time for them to pick up new shows.
I grew up with free television. Now, it wasn't free, there was these commercials, and so the economic model was driven through commercials and through advertising.
Time is money, as they say, and it was never more apropos than on a television show, where a minute is worth about $200!
When we started looking at the bigger television ecosystem, you see that there's not that many serialized TV shows being made for TV. The economics are lousy: They don't sell into syndication well; they're expensive to produce.
I think that 'Lost' is a bit of a dinosaur in terms of the type of show it is. The economics just don't support making a show this big and complicated profitable enough for a network.
Somebody once told me - and I could be wrong about this - that The West Wing was, on any given episode, $300,000 over, on average. Now today, if you were $10,000 over budget, they would cancel you. For sure.
It's just unfortunate that a network only makes their profit off of live viewership because their hands are tied by advertisers. They may believe in the show and want it to continue, but they just unfortunately can't afford it.
The economics of television syndication and DVD sales mean that there's a tremendous financial pressure to make programs that can be watched multiple times, revealing new nuances and shadings on the third viewing. Meanwhile, the Web has created a forum for annotation and commentary that allows more complicated shows to prosper, thanks to the fan sites where each episode of shows like 'Lost' or 'Alias' is dissected with an intensity usually reserved for Talmud scholars.
