After being acquired by the causal game company iWin in 2016, Gamezebo was redesigned and expanded its coverage to PC games. It is based in Walnut Creek, California. Gamezebo was launched in 2005. It was founded by Joel Brodie, the former head of business development at Yahoo! Games.

In 2008, it held another installment of the Zebbys which was aired on Lifetime and was nominated for a Webby Award for 'Games-Related' websites. It used RSS for its content feed. In 2009, Gamezebo expanded its scope with the growing popularity of social games such as FarmVille (2009). By February 2010, it had a staff and twenty freelance journalists. The website was redesigned in 2014.In 2015, editor-in-chief Jim Squires told MacRumors that Gamezebo was struggling as larger mobile developers shifted away from traditional advertising. In March 2016, Gamezebo was acquired by casual game company iWin. It launched another redesign shortly after, improving navigation and expanding its coverage to PC games. Gamezebo, Inc. is based in Walnut Creek, California.
