Additionally, the historic Kabel typeface, which MTV displayed at the beginning and end of all music videos since 1981, was phased out in favor of larger text and less information about the video's record label and director. The classic font can still be seen on videos airing on MTV Jams, and in "prechyroned" versions of old videos on sister network VH1 Classic, which had their title information recorded onto the same tape as the video itself.
