HBO, also known as the Home Box Office, is the television station which own the Talent Associates, the group who own the rights to the first iteration of Supermarket Sweep, which aired on the ABC Network between 1965 and 1967.
A lack of preservation[]
Seven episodes of the original Supermarket Sweep are all that remain, after almost all episodes were wiped, mostly due to a lack of "moving image" preservation techniques used earlier than 1970.
