What year did the superbowl start being played in feb instead of jan

The first Super Bowl was played January 15, 1967, which was the third Sunday of the month. Over the years the game has been pushed back to the fourth Sunday in January and finally to the first Sunday in February where it is held today. Schedule changes, addition of the bye week and expansion of the playoffs necessitated these changes. Super Bowl XXXVI in 2002 was the first played in February. It was played in January in 2003, and has been played the first Sunday every February since 2004.
