Here in Canada we don’t get Comedy Central (it’s Comedy Network, different programs and such). The new season of Futurama is 16 episodes. Groening decided to split the season into four movies (which for tv can be divided into four episodes). 4 movies at 4 episodes a movie equals to 16 episodes.
fyi, the movies/seasons are: Bender’s Big Score, The Beast with a Billion Backs, Bender’s Game, and Into the Wild Green Yonder. Look for them on dvd.
