The blog, launched in 2002, was originally edited by Peter Rojas, who was later recruited by Weblogs, Inc. to launch their similar technology blog, Engadget. By mid-2004, Gizmodo and Gawker together were bringing in revenue of approximately $6,500 per month.
In 2005, VNU and Gawker Media formed an alliance to republish Gizmodo across Europe, with VNU translating the content into French, German, Dutch, Spanish, Italian and Portuguese, and adding local European-interest material.
In 2006, Gizmodo Japan was launched by Mediagene, with additional Japanese contents.
In April 2007, Allure Media launched Gizmodo Australia, under license from Gawker Media and incorporating additional Australian content.
In November 2007, the Dutch magazine license was taken over by HUB Uitgevers.
In September 2008, Gizmodo Brazil was launched with Portuguese content.
In September 2011, Gizmodo UK was launched with Future, to cover British news.
In February 2011, Gizmodo underwent a major redesign.
A Gizmodo blogger captured the first photos from the floor of the International Consumer Electronics Show (CES) 2007, and according to Reuters, journalists at the (simultaneous) Macworld debated whether Gizmodo or Engadget had the better live coverage of Steve Jobs' 2007 keynote.
Richard Blakeley, a videographer for Gizmodo's publisher, Gawker Media, disrupted several presentations held at the CES electronics trade show in 2008. Blakely secretly turned off flatscreen TVs using TV-B-Gone remote controls, resulting in his being barred from CES 2008, and any future CES events.
iPhone 4 prototype
In April 2010, Gizmodo came into possession of what was later known to be a prototype of the iPhone 4 smartphone by Apple, Inc. The site purchased the device for US$5,000 from Brian J. Hogan, who found it unattended at a bar in Redwood City, California, a month earlier. UC Berkeley student Sage Robert, an acquaintance of Hogan, allegedly helped him sell the phone after failing to track down the owner. With Apple confirming its provenance, bloggers such as John Gruber and Ken Sweet speculated that this transaction may have violated the California Penal Code.
On 26 April, after Gizmodo returned the iPhone to Apple, upon Apple's request, California's Rapid Enforcement Allied Computer Team executed a search warrant on editor Jason Chen's home and seized computers, hard drives, servers, cameras, notes, and a file of business cards, under direction from San Mateo County’s Chief Deputy District Attorney Stephen Wagstaffe. Since then, Gizmodo and the prosecution have agreed that a special master will review the contents of the items seized and determine if they contain relevant information. Gizmodo was since barred from Apple-hosted events and product launches until August 2014, when they were invited once again to Apple's September 2014 "Wish we could say more" event.
