Optimum Lightpath Creates First Video-on-Demand Channel Dedicated to Educating Businesses on Advantages of Metro Ethernet.

Unique Approach Allows Decision-makers to Learn About Metro Ethernet Business Services at Their Convenience, Through Long-Form VOD Content and Advanced Interactive Tools

JERICHO, N.Y. -- Optimum Lightpath, the next-generation business broadband service provider of Cablevision Systems Corporation (NYSE: CVC), today announced the launch of the first video on demand (VOD) channel specifically designed to educate businesses on the benefits of Metro Ethernet. Accessible on Cablevision's iO([R]) channel 660, the specialized programming will reach more than 2 million iO digital cable customers in Optimum Lightpath's service area of Northern New Jersey, Westchester, Connecticut, Long Island, the Bronx and Brooklyn. Optimum Lightpath will be reaching business decision-makers in their homes with clear, compelling, non-technical content that they can access to learn more about Metro Ethernet.

This innovative business-to-business marketing initiative from Optimum Lightpath includes interviews with telecommunications industry luminaries such as Ethernet inventor Robert Metcalfe and Metro Ethernet Foundation (MEF) President, Nan Chen. Other segments feature educational content from Optimum Lightpath executives as well as customer success stories. The channel was created to communicate the many benefits of Metro Ethernet including reliability, scalability, and substantial cost savings.

With this unique channel, Optimum Lightpath hopes to further accelerate the demand for Metro Ethernet services, a market that industry analyst Frost & Sullivan estimates will grow from $866.2 million in 2005 to $3.4 billion in 2012 across North America - an increase of nearly 300 percent.

"The demand for high-speed, high-capacity networks continues to accelerate, driven by mission critical, high bandwidth applications. Businesses are now becoming aware that Carrier Ethernet services offer tremendous flexibility and cost-advantage for enterprise data delivery," said Nan Chen, President, Metro Ethernet Forum. "Optimum Lightpath's use of a dedicated VOD channel for Carrier Ethernet is an innovative initiative to educate New York area businesses and we are pleased to see our members striking new ground."

Optimum Lightpath's VOD program "Metro Ethernet Now" is targeted to business decision makers and serves to explain how and why Metro Ethernet delivers higher productivity, lower capital and operational expenditures.

"Metro Ethernet makes organizations more productive, while providing cost-savings and operational efficiencies. It is an innovative communications technology that will really benefit from an innovative channel conveying its many compelling benefits. Our iO channel 660 serves this purpose - providing a wealth of relevant information that business executives can view at their leisure," said Dave Pistacchio, executive vice president and general manager, Optimum Lightpath. "Optimum Lightpath's leadership in Metro Ethernet made it particularly important for us to develop a cutting-edge approach to raising awareness of the value of this technology. Our experience has been that businesses that migrate to Metro Ethernet will never want to return to antiquated communications technology."

Prospective customers and others who cannot access iO channel 660 will be able to view the channel in its entirety by logging onto www.optimumlightpath.com/vod.

To support their commitment to Metro Ethernet, Optimum Lightpath has launched a promotion giving qualified companies that switch to the technology a credit on the first month of service, a free managed Cisco router and free fiber build-out to their business. This offer is in the market through April 30.
