The Legacy. Before the Adventures of Rin Tin Tin, there were 17,400 German Shepherds registered with the AKC. After the show finished its prime time run in 1959, that number increased to 33,735, illustrating the effect on the breed of the popularity of the show. In the early 1970’s the show was re-released with the addition of introductions to the episodes, and after editing designed enhance the appeal of Rin Tin Tin to a new generation of children. No longer in prime time, it still ran 5 times a week in 85% of the country. Many memories people have of Rin Tin Tin come from that re-release and not the original run. Next: The Return?
