RedTube is a pornographic video-sharing site, which in September 2009 held an Alexa ranking within the world's top 100 sites. It is one of several pornographic websites owned by Aylo. In June 2010 it had fallen out of the top 100, but it made a return in mid-2012. As of mid September 2020 its Alexa ranking was 520. Its popularity has been ascribed to its non-sexual name, which is a reference to the non-pornographic video sharing website YouTube. The website is based in Houston, Texas, and has servers in San Francisco, New Orleans and Montreal.
