Google Translate is a multilingual service provided by Google Inc. to translate written text from one language into another. It supports 90 languages. Before October 2007, for languages other than Arabic, Chinese and Russian, Google Translate was based on SYSTRAN, a software engine which is still used by several other online translation services such as Yahoo! Babel Fish, AOL, and Yahoo. Since October 2007, Google Translate has used proprietary, in-house technology based on statistical machine translation instead. On May 26, 2011, Google announced that the Google Translate API for software developers had been deprecated and would cease functioning on December 1, 2011, “due to the substantial economic burden caused by extensive abuse.” Because the API was used in numerous third-party websites, this decision led some developers to criticize Google and question the viability of using Google APIs in their products. In response to public pressure, Google announced on June 3, 2011, that the API would continue to be available as a paid service. The company stated in 2013 that it served 200 million people daily.
