Cablevision has joined the ranks of service providers who are offering a Caller ID on TV service to customers.

Cablevision said today that TV Caller ID will be available to all of its iO digital cable customers tomorrow, after previously launching the service in its Long Island, New Jersey and New York footprint.

The service, which is available at no additional charge to Cablevision’s customers, lets subscribers see incoming calls in a small box in the upper left corner of their TV screens.

The display is present for approximately seven seconds, allowing customers to decide if they want to take the call while continuing to watch TV, without any interruption or without having to hunt around for the phone

"iO TV customers with Optimum Voice will now immediately know who is calling just by looking at the television set," said John Trierweiler, Cablevision's SVP of product management. "Caller ID on iO TV is a meaningful enhancement that underscores Cablevision's leadership in delivering the most technologically advanced digital services to our customers over our fully deployed fiber optic network."

Several years ago Time Warner Cable rolled out a Caller ID on TV service in its New York division that was developed by the cable company. Since then the TV Caller ID has been implemented in several TWC divisions.

Integra5 has also deployed the service with several smaller service providers and plans to provision Caller ID on a PC, as well. Studies by Integra5 have shown that blended services are well received by customers and can reduce churn in the face of competition.
