January 21, 1954 - The world's first nuclear-powered submarine, the USS Nautilus, was launched in Groton, Connecticut by Mamie Eisenhower, the First Lady of the United States. The vessel was named after the submarine in Jules Verne's Twenty Thousand Leagues Under the Sea. Because nuclear propulsion allowed her to remain submerged for longer than diesel-electric submarines, the Nautilus was capable of traveling to locations previously beyond the limits of submarines. The Nautilus was the first vessel to complete a submerged transit across the North Pole.

 January 22, 1984 - Apple Computer introduced the Macintosh, the first computer to popularize the computer mouse and the graphical user interface, during Super Bowl XVIII with its famous "1984" television commercial. Based on George Orwell's dystopian novel 1984, the commercial used an unnamed heroine to represent the coming of the Macintosh as a means of saving humanity from conformity. The heroine runs past rows of minions and hurls a sledge hammer through a large screen broadcasting a speech by Big Brother. It was the only daytime televised broadcast of the commercial in the United States. The ad ran one other time, in December, 1983 in Twin Falls, Idaho, so that the commercial could be submitted to award ceremonies for that year. Despite its limited broadcast it is widely regarded as one of the most memorable and successful American television commercials of all time. You can watch the commercial here. 

January 25, 1924 - The first Winter Olympics opened in Chamonix, France. The games featured 16 events in seven different sports, including Bobsleigh, Curling, Figure Skating, Ice Hockey, Military Patrol, Nordic Skiing and Speed Skating.  Some of the sports, namely Figure Skating and Ice Hockey, were Olympic sports at previous summer Olympic games, but were limited by the season. Charles Jewtraw of the United States was the first ever recipient of a Winter Olympic gold medal, winning in the 500 meter Speed Skating. At the closing ceremonies a prize in mountaineering was also presented to Charles Granville Bruce, the leader of the expedition that tried to climb Mount Everest in 1922.
