Scooby-Doo, Where Are You! (lost original broadcast episodes; 1969)

Scooby-Doo, Where Are You! is the first ever incarnation of the Scooby Doo series. Produced for CBS, the series premiered as part of the network's Saturday morning schedule on September 13, 1969, and aired for two seasons until October 31, 1970. In 1978, a selection of episodes from the later series Scooby's All-Stars and The Scooby-Doo Show were aired on ABC under the Scooby-Doo, Where Are You! name and they were released in a DVD set marketed as its third season.

Summary
In the mid-1990s, Hanna-Barbera Productions released several remastered versions of Where Are You?, noted by the use of their then-current "Comedy" All-Stars logo. Currently, only one episode has been remastered in its original 1969 broadcast: the episode "Go Away Ghost Ship". The others, as well as all eight season two episodes, are presumed to be unviewable in their original broadcast. The reprints are easily noticeable due to there being a lower pitch than the originals. It is unknown if the other original 1969 broadcast episodes will ever see restoration.
