“Hop-along Cassidy” is a fictional cowboy hero created in 1904 by
the author Clarence E. Mulford, who wrote a series of short stories
and novels based on the character.

In the first film, Hopalong Cassidy (then spelled "Hop-along") got
his name after being shot in the leg. Hopalong’s "drink of choice"
was the nonalcoholic sarsaparilla.

From 1949 to 1953, NBC aired 52 theatrical films of "Hopalong
Cassidy". This series, consisted of 40 new episodes made for
TV, a half-hour in length, plus 12 additional theatrical features
that were edited to fit the 30-minute time slot.
