NEW YORK (AP) _ Peter A. Lund, executive vice president of the CBS Broadcast Group since 1990, was named president of the CBS Television Network.

Lund will oversee TV network sales, marketing and communications, as well as relations with network affiliates.

Continuing to report to Lund will be the network's television stations and radio divisions.

The television network president's job has been vacant since 1988, but CBS Broadcast Group President Howard Stringer said Monday it was time to revive it. ''The value of a 'network' has never been more obvious,'' Stringer said, citing the success of CBS' Winter Olympics coverage, ''Late Show with David Letterman,'' and its prime-time and daytime programming.

''With that in mind, we will formally reinstate the 'network' division,'' he said.

Lund joined CBS in 1977 as vice president of the network-owned radio stations. He has worked for CBS in a number of capacities since then, with time out from 1987 to 1990, when he was president of Multimedia Entertainment, which produces and distributes syndicated programs such as ''Donahue'' and ''Sally Jessy Raphael.''
