First, reality television (thanks, Britain!) is cheap, and, though it doesn't repeat well, it consistently occupies at least a third of any schedule. In fact, the buys this year reflect a decrease not only in narrative comedy, but in scripted programming in general. It's just no fun owning this kind of stuff when DVD sales are flattening out, repeats are not delivering, and international buyers are not keen.

In addition, the networks have picked up quite a few spin-offs of existing dramas this year, thus cutting costs by doubling up on writing and production staff, and reducing the need for new ideas.

On top of all that, the smart money is betting there will be a Writers Guild of America strike in October, which is not funny for the networks, and for which they are preparing by arming themselves with increasing amounts of "reality".
