Yahoo! Babel Fish was a free web-based multilingual translation application. In May 2012 it was replaced by Bing Translator, to which queries were redirected. Although Yahoo! has transitioned its Babel Fish translation services to Bing Translator, it did not sell its translation application to Microsoft outright. As the oldest free online language translator, the service translated text or web pages between 38 languages, including English, Simplified Chinese, Traditional Chinese, Dutch, French, German, Greek, Italian, Japanese, Korean, Portuguese, Russian, and Spanish.
