Trek's original pilot (called "The Menagerie", but later re-titled "The Cage" since that became the title of a later episode) was not well received at NBC, and NBC famously paid for a second pilot episode, something that had never happened in TV history to that time. The next time this would happen would be when this series' first pilot "Justice for All" met with disappointment at ABC, prompting CBS to nab the show and commission a new pilot with the likes of Sally Struthers and Rob Reiner in supporting roles. Identify this landmark sitcom which premiered in 1971, running for nine seasons.
