Following Heroes' worst ratings performance ever for a new episode this week, NBC has announced that it's combining the show with returning spy comedy drama Chuck in January.

Chuck will air from 8-9 p.m. on Monday evenings, with Heroes following from 9-10 p.m. Both series will kick off 2010 with a two-hour "event": Heroes will air a special two-hour edition on January 4th, while Chuck's return will be marked with a two-hour launch on Sunday January 10th, heavily promoted during the NFL games being shown the day before.

The November 17th episode of Heroes, broadcast at 8 p.m. only achieved 5.07m viewers, beaten by House on Fox, and two comedies on ABC.

ABC has also confirmed that the final season of Lost will air on Tuesday nights at 9 p.m., starting on February 2nd with a two hour episode dubbed LA X.
