According to Wikipedia:
Livestream, formerly known as Mogulus, is a live streaming video platform that allows users to view and broadcast video content with only a camera and a computer through the internet. It offers a free ad-supported service and multi-tiered premium services for organizations and media professionals.
Livestream also offers wireless HD broadcasting in the form of a device combination called Livepack, described as “a satellite television truck in a backpack.”
In September 2009, Livestream started providing custom channel pages for special streaming video events like concerts from Pixie Lott and David Gray. These pages integrated live chat, Twitter, and Facebook. Livestream has been used to stream content by Gannett Newspapers and by the World Economic Forum, and some local TV affiliates, usually for local news and storm watch.
