ET is looking back at Mork & Mindy -- the show that made Robin Williams a star.
PICS: Remembering Robin Williams
In 1978 the world was introduced to the alien character Mork, which stole the show when it debuted on Happy Days. The character became so popular that it warranted its own spinoff which premiered later that same year. The series went four seasons before it was canceled in 1982.
The impact that Mork had on television viewers had a lasting effect that continued to resonate throughout Williams' career.
"You know, it's weird," Williams told us. "Even after I won an Academy Award, it was a week later there were still people going, 'Mork!'" Robin told us.
