Optimum Online Ranked Top High-Speed Internet Service Provider in the East By J.D. Power and Associates in 2008 Internet Service Provider Residential Customer Satisfaction Study(SM)

BETHPAGE, N.Y., Oct. 30 /PRNewswire-FirstCall/ -- Cablevision Systems Corp., today announced that its Optimum Online high-speed Internet service has been named the top high-speed Internet service provider in the East Region in the J.D. Power and Associates 2008 Internet Service Provider (ISP) Residential Customer Satisfaction Study(SM). The study, which ranked ISPs based on customer satisfaction across a range of key product attributes including performance and reliability, cost, customer service and billing, scored Optimum Online higher than all other Broadband providers and phone companies in Cablevision's Region.

The study, released by J.D. Power and Associates earlier today, found that Optimum Online performed "particularly well in offerings and promotions and performance and reliability." Cablevision announced this week that standard pricing for Optimum Online will not increase in 2009, the sixth year in a row without a price increase for this top-ranked service, which is also the most highly-penetrated broadband service in the nation, with more than 51 percent of the homes passed by Cablevision's fiber optic network connecting to the Internet through Optimum Online, and a broadband market share of approximately 75 percent in Cablevision's service area.

"There's a reason why more than half of the homes passed by our fiber optic network access the Internet through the fast and reliable connections provided by Optimum Online, and it is extremely gratifying to have our enduring commitment to speed, quality and value - already familiar to our customers - recognized by J.D. Power and Associates," said John Bickham, Cablevision's president of cable and communications. "Even with the success of this service, we have continued to find ways to exceed our customers' expectations, whether through a significant free speed increase a few years ago or, more recently, by becoming the only broadband provider in the country to extend the value of its product by offering customers free WiFi access in commercial and high-traffic locations across its service area."
