CBS cancels B Positive after two seasons

Deadline

B Positive marks the second cancelation of a Chuck Lorre comedy in the past 24 hours, after fellow sophomore sitcom United States of Al was also canceled last night. Because of Lorre's standing at CBS, B Positive -- which underwent a creative for Season 2 -- was expected to be renewed. Lorre will still have two comedies on CBS' schedule next season: No. 1 comedy Young Sheldon and Bob Hearts Abishola.
