Giant Interactive Group Inc operates and develops online games, primarily its blockbusterMMO ZT Online 2, in China. As of 2008, the company has a strong presence in 2nd and 3rd tier Chinese cities, large and medium sized cities that aren't one of the top four in terms of population and contribution to GDP. In 2008 Giant Interactive had the third-largest share of the Chinese online games market with 11.9%, and a BNP Paribas media unit called the company "the industry leader of online games in China." It was founded in 2001 as Shanghai Zhengtu Network Technology Co Ltd.
Listed on the NYSE in 2007, in late 2013 the company was planning to be taken private (and subsequently delisted from the exchange). As of April 2014, this go-private plan had yet to be completed amid a lawsuit filed by shareholders to prevent the sale.
