The Washington Post Co., in a move to expand its video operations yesterday announced creation of a new Post-Newsweek Video division.

The new division will consolidate operations of Newsweek Video, a part of Newsweek Inc., and Post-Newsweek Productions, which has been a part of Post-Newsweek Stations Inc. The new division will have its own board of directors.

Alan Perris, currently president of Post-Newsweek Productions, was named president of the new division. In a statement issued by the Post, Perris said "We hope to accelerate our development of programs for cable and over-the-air television. We also will intensify our search for programming that we can purchase for syndication."

However, Perris stressed that the new division will focus on developing news and information programs, not entertainment shows, to take advantage of the company's strengths in the information field.

The syndication and production activities of Newsweek Video and Post-Newsweek Productions will continue in the new division. Newsweek Video produces "Newsweek Women," which is carried by Hearst/ABC, as well as the syndicated news inserts "Feature Service" and "Today's Woman."

Post-Newsweek Productions produces "The Charlie Rose Show" and syndicates "Agronsky & Co." and "Sonya," which is produced by the Post-Newsweek station WDIV in Detroit and carried daily by the USA Cable Network.

On the new division's board of directors are Joel Chaseman, president of the Post-Newsweek Stations Inc., who will serve as chairman; Martin Cohen, vice president-finance and treasurer of the Washington Post Co.; Mark M. Edmiston, Washington Post Co. vice president; Benjamin C. Bradlee, executive editor of The Washington Post; Alan G. Spoon, Washington Post Co. vice president; and Perris.
