Joss Whedon
Angel was a spin-off of Buffy the Vampire Slayer. The series was named after Buffy's vampire-with-a-soul boyfriend. It was created by Whedon and David Greenwalt. Tim Minear also helped at times. First shown in September 1999 on the WB, the series was on after Buffy on Tuesday evenings. When Buffy switched networks in 2001, Angel aired in a number of different time slots. The series' last episode had more people watching than the final Buffy episode. Joss Whedon was briefly in the series as the character 'Numfar' in its second season. The WB cancelled the series in May 2004 while it was in its fifth season. As Whedon had not planned to end Angel, he had to change the story and ending of both the final season and the series.
