Fox has renewed “Malcolm in the Middle” for a seventh season, the network announced Friday. The Sunday night comedy has slipped in the ratings during the past couple years, and creator/executive producer Linwood Boomer has said the next season could be the last. Mr. Boomer also signed a development deal with Regency Television, which produces the series.

“We couldn’t be prouder and happier to have one more year to annoy people,” Mr. Boomer said in a statement.
