JibJab is an American independent digital entertainment studio based in Los Angeles, California. Founded in 1999 by brothers Evan and Gregg Spiridellis, it first achieved widespread attention during the 2004 US presidential election when their video of George W. Bush and John Kerry singing "This Land Is Your Land" became a viral hit. Initially known for political and social satire, JibJab produced commercials and shorts for clients such as Sony, Noggin, Cartoon Network, Nickelodeon, PBS Kids, Sprout, NBC, Qubo, and Disney before focusing on its now-flagship personalized eCard and messaging services. In 2016, its animated sticker-making program – which has been available since 2004 – became the top App Store app by download growth.
