Thames' first foray into home video was as hasty, if not more so:

Woah, The Benny Hill Show had a video release?

Read the description. "The Best of the Benny Hill Show", so probably just a compilation. It was 1981 apparently, Hill had only been at Thames for a decade or so at that point, having pottered around between the BBC and two ITV companies in the 60s for some reason.

The Thames episodes were later released on DVD by Network and somebody else (it says here) released what still existed of his shows on the BBC in America. Hill had a stint at ATV as well, but probably safe to assume those episodes had an accident with a charged magnetic eraser head in a video machine somewhere.
