NEW YORK (AP) -- The CBS Sunday political talk show "Face the Nation" will soon match its rivals in length.

Anchor Bob Schieffer said Sunday that the show will become an hour in April. It currently airs for a half an hour.

Both of its competitors, NBC's "Meet the Press" and ABC's "This Week," are already an hour in length. CBS is making the change at a time "Face the Nation" has been doing well in the ratings.

Schieffer didn't mention it, but it's not entirely certain the change will be permanent. CBS News President David Rhodes says the extended length will last at least through the political conventions next summer, and then be evaluated.
