companion conference, TEDGlobal, held in the UK each summer. The 2009 TEDGlobal, The Substance of Things Not Seen, was held in Oxford, July 21–24, 2009. 2010's TEDGlobal (again in Oxford) was themed And Now The Good News; in 2011 the conference moved to a new home in Edinburgh and was held July 12–15 with the theme The Stuff Of Life. The 2012 TEDGlobal conference Radical Openness was held in Edinburgh, June 25–29. TED Translators TED Translators, formerly known as the Open Translation Project (OTP), started as the TED Open Translation Project in May 2009. It intends to "[reach] out to the 4.5 billion people on the planet who don't speak English", according to TED Curator Chris Anderson. The OTP used crowd-based subtitling platforms to translate the text of TED and TED-Ed videos, as well as to caption and translate videos created in the TEDx program. (Until May 2012 it worked with its technology partner dotSUB, and then with the open source translation tool Amara). When the project was launched, 300 translations had been completed in 40 languages by 200 volunteer transcribers. By May 2015, more than 70,000 sets of subtitles in 107 languages had been completed by (an all-time total of) 38,173 volunteer translators. The project helped generate a significant increase in international visitors to TED's website. Traffic from outside the US has increased 350 percent: there has been 600 percent growth in Asia, and more than 1000 percent in South America. Members have several tools dedicated to knowledge management, such as the OTP Wiki OTPedia, Facebook groups, or video tutorials. TEDx TEDx are independent events similar to TED in presentation. They can be organized by anyone who obtains a free license from TED, and agrees to follow certain principles. TEDx events are required to be non-profit, but organizers may use an admission fee or commercial sponsorship to cover costs. Speakers are not paid and must also relinquish the copyrights to their materials, which TED may edit and distribute under a Creative Commons license. As of January 2014, the TEDxTalks library contained some 30,000 films and presentations from more than 130 countries. As of October 2017, the TEDx archive surpassed 100,000 talks. In March 2013, eight TEDx events were organised every day; raised up from five in June 2012, the previous year, in 133 countries. TEDx presentations may include live performances, which are catalogued in the TEDx Music Project. In
