'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.
