Fox's previews and promotions for newly minted hit "24" are giving away too much. Last week's previews robbed this week's episode of a surprise ending, giving away a gruesome discovery in a car trunk.

Fox isn't alone. Earlier this fall The WB showed previews for a "Gilmore Girls" episode, including scenes of Rory crying on a dance floor, a scene that came in the show's last 10 minutes.

Promotion is necessary, of course, but networks should adhere to a 20-minute rule, limiting scenes used in previews to those from the first 20 minutes of a given episode.
