Episode guide Season 1 (1986–87) Season 2 (1987–88) Broadcast history Adderly aired from September 1986 through May 1987 (its first season) in the 11:30pm CBS Late Night slot on the CBS network. For the second season (beginning in August 1987), the show's popularity prompted CBS to run episodes in prime time, but there was little promotion and the show didn't do well in the ratings. CBS moved the show back to the 11:30pm time slot in September 1987 where it remained until the series ended. Canadian broadcasts of the series did not commence until January 1987.
