Ustream is a website that allows members to broadcast live streaming video on the Internet. 

Members can broadcast directly from the Ustream website or from a mobile device using Ustream's mobile broadcasting application (available for Android and iPhone). Ustream members can also record and save videos for future broadcast distribution.  Ustream's video platform is known for its ability to provide viewers with different ways to interact with the presenter during a live broadcast, providing broadcasters with chat and instant polling features, as well as allowing integration with Twitter and Facebook news feeds. 

Ustream was initially conceived as a way to connect soldiers overseas with their families back home. Founders John Ham and Brad Hunstable, together with partner Gyula Feher, felt that a product like Ustream would provide soldiers with a way to talk to all of their relatives simultaneously during their limited free time in the war zone. 

Ustream attracts more than 50 million unique monthly users, making it the world's largest live streaming platform. The top industries taking advantage of Ustream's live streaming are politics, entertainment and technology fields. Ustream's searching feature allows visitors to filter through video categories such as sports, entertainment, news, animals, music, technology, games and education. Members can elect to be notified by email about future live videos on topics of interest.
