One of the most significant communication-related events of the early 20th century happened in March of 1933, although nobody at the time would have had any way of knowing that quite yet.
It was then that President Franklin D. Roosevelt, as a result of the Great Depression, addressed the nation for the first time during one of his famous “Fireside Chats.” Just a few days later, on March 15, the Dow Jones Industrial Average rose from 53.84 to 62.10. Despite the fact that the country was still in the throes of the Depression itself, this gain of 15.34% still marks the largest single-day percentage gain for the index in its history.
