There is widespread agreement that "WKRP in Cincinnati" was one of the greatest television sitcoms ever produced. The original episodes are rightly considered to be a national treasure and cultural landmark.
Copyright law madness has destroyed it forever - plain and simple.
WKRP was created at a time when mass consumer home video was unheard of. As a result, the much of the music was only licensed for a limited number of years for use on broadcast television. You would think that by licensing the music, a derivative work such as a television show would have a fair use right to continue to use the music in order to preserve the artistic integrity that was vital for show to continue to exist. You would think that – but you'd be wrong. Within the maddening culture of entertainment legal affairs, the music licenses did not entitle the episodes to continue to use the music in other mediums in the future. The only way the show could be seen in the future was to destroy its original artistic vision and substitute other music tracks, which in some cases completely alter the feel of the scenes.
Most copies of the original show were destroyed – out of fear that if a tape were mislabeled and still contained the original music, then even a single accidental airing of the episode containing the original (unlicensed) music could subject the company to massive liability.
To make a long story short, WKRP is finally being released on DVD. However, they were not able to clear rights for the music. All the music used in the show has been replaced with generic Muzak.
Big surprise there...
