T3 magazine is a UK-based technology magazine, which specializes in gadgets, gizmos, and other technology.
Originally, T3 stood for Tomorrow's Technology Today, but this isn't used anywhere in the magazine or on the website anymore. It's exclusively referred to as T3 or T3.com. The magazine is popular but in terms of sales is ranked second among UK gadget magazines. T3 magazine is available in most countries, and has syndicated/localized versions in over 20 countries. Source
