'Lost' to Unravel Final Mystery

Lost will end in 2010, ABC announced yesterday, after three more seasons of just 16 episodes each. The unusual strategy is an attempt to reverse a ratings slump caused by scheduling shifts and a slew of increasingly baffling plot twists. Co-creator Damon Lindelof tells USA Today the team behind the show has "specific designs" for the rest of the run.

Lost's wall-to-wall mysteries re-energized ABC in 2004, but its changing fortunes led to the decision to wrap up in 2010, a move one producer called "practically unprecedented." The final seasons will run from February to May and unravel the secrets that have made Lost the most recorded show on DVR. (More Lost stories.)
