Wikipedia Zero is a project by the Wikimedia Foundation to provide Wikipedia free of charge on mobile phones via zero-rating, particularly in developing markets.[1][2] The program was launched in 2012,[3] and won a 2013 SXSW Interactive Award for activism.[4] The objective of the program is to increase access to free knowledge: in particular without data-usage cost.
Facebook Zero has been cited as an inspiration for Wikipedia Zero.[5]
