Good Luck Charlie is an American sitcom that originally aired on Disney Channel from April 4, 2010, to February 16, 2014. The series' creators, Phil Baker and Drew Vaupen, wanted to create a program that would appeal to entire families, not just children. It focuses on the Duncan family of Denver as they adjust to the births of their fourth and fifth children, Charlotte "Charlie" (Mia Talerico) and Toby (Logan Moreau). In each episode, Teddy Duncan (Bridgit Mendler) adds to a video diary that contains 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 for future reference. Each video diary ends with Teddy (or another family member, 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, in Canada on April 5, 2010, in the United Kingdom and Ireland on May 14, 2010, and in Australia and New Zealand on July 23, 2010. In March 2011, a feature-length Christmas Disney Channel Original Movie based on the series, entitled Good Luck Charlie, It's Christmas!, began production for a December 2011 premiere.
