Since its inception in 1921, the White House Correspondents' Association Dinner has provided a snapshot into the current state of affairs in both the media and the presidency. As this year's dinner approaches, we're taking a look back at those defining moments, whether they be groundbreaking or uncomfortable.
1924: Calvin Coolidge becomes the first president to attend the White House Correspondents' Association Dinner. The dinner was held in the Old Arlington Hotel and 50 people attended.
1930: The dinner is canceled when Chief Justice William Howard Taft, a former president himself, dies on the day of the event, March 8.
1941: President Franklin D. Roosevelt delivers the most important speech ever given at the dinner, calling for a commitment to fight the Axis powers. FDR explained his reasoning for using this occasion: "It differs from the press conferences that you and I hold twice a week, for you cannot ask me any questions tonight, and everything that I have to say is word for word on the record."
1942: One year after FDR's speech, the dinner is canceled for World War II. The next year, the dinner would be rationed and the president would have to buy his own ticket to attend.
1946: Attire returns to black-tie and food is no longer rationed.
1950: To protest the dinner's exclusion of women, Navy Undersecretary Dan Kimball hosts a separate dinner for the "underprivileged ladies" of the WHCA.
1951: President Truman asks the WHCA to cancel the dinner because of the "uncertainty of the world situation."
1954: Irving Berlin unveils an original song, "I Still Like Ike," to honor President Eisenhower.
1955: Dinner tops 1,000 for the first time.

1972: First lady Pat Nixon stands in for the absent president.
1975: Former feminist protester Helen Thomas become first female president of the WHCA. In her honor, Danny Thomas is asked to perform. Much to the audience's discomfort, his act is identical to his sexist routine in Las Vegas.

Obama said of the teen heart throb brothers' band, "Sasha and Malia are huge fans, but boys, don't get any ideas. Two words for you: predator drones. You will never see it coming. You think I'm joking?"
