The first "Power Rangers" entry, "Mighty Morphin Power Rangers", debuted on August 28, 1993, and helped launch the Fox Kids programming block of the 1990s, during which it catapulted into popular culture along with a line of action figures and other toys by Bandai. As of 2010, the media franchise has generated over $5 billion in retail sales worldwide.  - Space Sheriff Shaider (  Uch Keiji Shaid ) was a tokusatsu television show that aired on from 1984 to 1985 .
