Viacom to be key content partner with Joost™, the world's first online global tv distribution platform

Popular Programming from MTV Networks, BET Networks and Paramount Pictures Will Be Available for Joost's Launch

New York - February 20, 2007 - Viacom Inc. (NYSE: VIA and VIA.B), a leading global entertainment company, and Joost™ (www.joost.com), the world's first broadcast-quality Internet television service, announced today that Viacom will be a key content partner and will offer a full range of brands and programming for free to consumers on the innovative Joost distribution platform. Under the agreement, Viacom's divisions - MTV Networks, BET Networks and Paramount Pictures - will provide television and theatrical programming on the Joost platform. Founded by Niklas Zennström and Janus Friis, Joost is powered by a secure, efficient, piracy-proof Internet platform that enables premium interactive video experiences while guaranteeing copyright protection for content owners and creators. The financial terms of the deal were not disclosed.

Joost will allow users to have free access to thousands of programs and channels not readily available on the Web. Through Joost, viewers can watch programming from many of Viacom's brands on their computers through a customizable platform with advanced television viewing features such as links that lead to more information or related websites based on the content; and a variety of plug-in applications, such as instant messaging, message boards, and news tickers.

Currently available in limited beta, Joost combines the best of TV and the best of the Internet by offering viewers a unique, TV-like experience enhanced with the choice, control and flexibility of Web 2.0. Joost is the first online, global TV distribution platform, bringing together advertisers, content owners and viewers in an interactive, community-driven environment. Joost can be accessed with a broadband Internet connection and offers broadcast-quality content to viewers for free.

"We're extremely pleased to be working with Joost, and couldn't be prouder to be a key partner in the launch of the next generation in broadband video technology," said Philippe Dauman, Viacom President and Chief Executive Officer. "We have the number one portfolio of entertainment sites in the world and unrivaled distribution on mobile devices, but we're determined to keep pushing and growing our digital presence and bring our programming to audiences on every platform and device that they want. In addition to strong partnerships we have with traditional distributors, we will continue to seek out partners like Joost, which has created an exciting breakthrough platform that represents not only a fantastic user experience, but one that is built on a compelling and sustainable business model that respects both content creators and consumers."

Janus Friis, founder of Joost said, "We built this platform from the ground up, with companies like Viacom in mind. Our platform provides scalable distribution, in a completely safe environment that protects the interest of content owners and advertisers, while delighting viewers. We're extremely excited about this partnership and look forward to enabling Viacom to reach new audiences for its new and classic programming."

Yvette Alberdingkthijm, executive vice president, content strategy and acquisition for Joost said, "Viacom's properties are perfectly suited to Joost. We're thrilled to be a part of Viacom's digital strategy."
