Kotaku is a video game website and blog that was originally launched in 2004 as part of the Gawker Media network. Notable former contributors to the site include Luke Smith, Cecilia D'Anastasio, Tim Rogers, and Jason Schreier.
Kotaku was first launched in October 2004 with Matthew Gallant as its lead writer, with an intended target audience of young men. About a month later, Brian Crecente was brought in to try to save the failing site. Since then, the site has launched several country-specific sites for Australia, Japan, Brazil and the UK. Crecente was named one of the 20 most influential people in the video game industry over the past 20 years by GamePro in 2009 and one of gaming's Top 50 journalists by Edge in 2006. The site has made CNET's "Blog 100" list and was ranked 50th on PC Magazines "Top 100 Classic Web Sites" list. Its name comes from the Japanese otaku (obsessive fan) and the prefix "ko-" (small in size).
In 2009, Business Insider reported that Hearst Corporation sought to buy Kotaku from Gawker Media.
Stephen Totilo replaced Brian Crecente as the editor in chief in 2012. Totilo had previously joined Kotaku in 2009 as deputy editor.
In April 2014, Gawker Media partnered with Future plc to launch Kotaku UK, and with Allure Media to launch Kotaku Australia.
Kotaku was one of several websites that was purchased by Univision Communications in their acquisition of Gawker Media in August 2016; Gizmodo Media Group was subsequently founded to house the Gawker acquisitions, operating under the Fusion Media Group, a division of Univision. The Gizmodo Media Group was later acquired by the private equity firm Great Hill Partners in April 2019, and renamed G/O Media.
In December 2018 Pedestrian Group, owned by the Australian media company Nine Entertainment, acquired Kotaku Australia. and continues to own it.
The transition to G/O Media led to several departures from the site, as well as from other sister sites under the former Gawker Media label due to conflicts with G/O Media's management.
