September 19, 1970 –

The greatest sitcom every produced, The Mary Tyler Moore Show, premiered on CBS TV on this date.
The lyrics to the theme song were rewritten after the first season. The first season’s theme song emphasized Mary’s challenge of being independent, such as with the line, “You might just make it after all.” However, with the series showing that Mary has become obviously successful in her own life, the lyrics reflected that change of tone such as with the line, “You’re going to make it after all.”
