SightSpeed
SightSpeed is a videoconferencing company, supplying VoIP and instant messaging software for Microsoft Windows and Apple Macintosh operating systems. The service allows people to make video calls, computer-to-computer voice calls, and calls to regular telephones, with free and paid versions.
In October 2008, the company was acquired by Logitech for $30 million. The Logitech Vid service is based on SightSpeed's technology. Due to competing software, the Logitech Vid video calling service will be discontinued as of 1 July 2013 and the downloading of the product has already been terminated. As a result, Logitech is no longer accepting new account registrations.
