The series that began the franchise, Mighty Morphin Power Rangers (an American adaptation of the 1992 Japanese Super Sentai Series, KyÅryÅ« Sentai Zyuranger), began broadcasting as part of the Fox Kids block of programing that aired on the FOX network. It lasted for three seasons (from 1993 to 1996).
The show averaged 4.8 million daily viewers in its first season, according to Nielsen ratings. 3. âWhen it premiered 20 years ago, it went on to redefine what was possible in a kidsâ show in terms of ratings, global appeal and pop-cultural relevance,â Elie Dekel, the president of Saban Brands, told Time magazine. 4. There have been more than 800 Power Rangers episodes and 18 different series.
