The Arsenio Hall Show has been canceled, CBS Television Distribution announced today. The show, Hall's triumphant return to TV, premiered in September to solid numbers and was renewed for a second season in February — a second season that won't happen after all thanks to a major decline in ratings. "While there are many loyal fans of the show, the series did not grow its audience enough to continue," CBSTD said in a statement. Well, that'll do it. Late-night TV: more shake-ups than you think!
