Boyd resumed production in 1946, on lower budgets, and continued through 1948, when "B" westerns were being phased out. Boyd thought Hopalong Cassidy might have a future in television, spent $350,000 to obtain the rights to his old films, and approached the fledgling NBC network. The initial broadcasts were so successful that NBC could not wait for a television series to be produced and edited the feature films to broadcast length. On June 24, 1949, "Hopalong Cassidy" became the first network Western television series.
