Good Luck Charlie is an original Disney Channel television sitcom, which premiered April 4, 2010. The series was created by Phil Baker and Drew Vaupen, who wanted to create a program that would appeal to entire families, as opposed to children only. It revolves around a Denver family, the Duncans, as they try to adjust to the birth of their fourth child, Charlotte "Charlie" Duncan (Mia Talerico). In each episode, Teddy Duncan (Bridgit Mendler) creates a video diary containing advice for Charlie about their family and life as a teenager. Teddy tries to show Charlie what she might go through when she is older in the video diaries for future reference. Each video diary ends with Teddy (or someone else from the family, even Charlie) saying the eponymous phrase, "Good luck, Charlie."
Among other decisions, executives included adult-centric scenes and changed the series title from Oops to Love, Teddy and finally to Good Luck Charlie in order to ensure the series would appeal to all family members. Good Luck Charlie premiered on Disney Channel in the United States on April 4, 2010. It premiered in Canada on April 5, 2010, the United Kingdom and Ireland on May 14, 2010, and in Australia and New Zealand on July 23, 2010. Good Luck Charlie was renewed for a second season, with production beginning in August 2010 with a season premiere on February 20, 2011. A feature-length Christmas Disney Channel Original Movie based on the series entitled Good Luck Charlie, It's Christmas! began production in March 2011 for a December 2011 premiere. On August 29, 2011, Disney Channel announced that they had renewed the series for a third season. The third season premiered on May 6, 2012.
