September 20 in history:

Explorer Ferdinand Magellan left Spain on September 20th, 1519, on a voyage to reach the Spice Islands by sailing west to reach the Pacific Ocean.  Magellan’s ships were the first ones to reach the Pacific from the Atlantic, and eventually, one ship, the Victoria, became the first to travel around the world to return to Spain.

Lewis and Clark were headed back from the Pacific Ocean toward the Mississippi when they reached a white settlement in Missouri on this date in 1806.  It took them another three days to reach St. Louis, ending the exploration of the Louisiana Territory which lasted more than two years.

The famous “Battle of the Sexes” tennis match between Bobby Riggs and Billie Jean King took place on September 20th, 1973 at the Houston Astrodome, before a crowd of 30-thousand and a worldwide TV audience. King was the defending women’s champion at Wimbledon.  Riggs won the men’s title at Wimbledon 34 years earlier.  The female pro defeated the older male pro in three straight sets.

ABC’s Howard Cosell was one of the broadcasters for the Riggs-King match that night.  Two years later, on September 20th, 1975, Cosell attempted to blaze a trail as a variety show host, when his new program called “Saturday Night Live” made its debut.  The more famous NBC show of the same name premiered three weeks later.
