In the early 21st century, the "Ofis ar Brezhoneg" ("Office of the Breton language") began a campaign to encourage daily use of Breton in the region by both businesses and local communes. Efforts include installing bilingual signs and posters for regional events, as well as encouraging the use of the Spilhennig to let speakers identify each other. The office also started an Internationalization and localization policy asking Google, Firefox and SPIP to develop their interfaces in Breton. In 2004, the Breton Wikipedia started, which now counts more than 50,000 articles. In March 2007, the "Ofis ar Brezhoneg" signed a tripartite agreement with Regional Council of Brittany and Microsoft for the consideration of the Breton language in Microsoft products. In October 2014, Facebook added Breton as one of its 121 languages, after three years of talks between the "Ofis" and Facebook.
