The "Get a Mac" advertising campaign was launched in April 2006 by TBWA/Chiat/Day to promote Apple computers over PCs. The campaign featured ads starring "Justin Long as Mac and John Hodgman as PC" and ran for 4 years through 2010, producing 66 television commercials that aired in the US, Canada, Australia, New Zealand, Japan, and UK. The ads focused on highlighting Mac's iconic design, operating system advantages, and user interface compared to PCs, which helped contribute to Apple gaining 42% growth in market share and selling 1.3 million Macs by the end of 2006.
