Joel Alan Chaseman, who led Post-Newsweek Stations Inc. as chief executive, died at the age of 93 on Saturday at his home in North Bethesda, Maryland.

Chaseman’s daughter, Joanne Bloomstein, said the cause was complications from a fall.

Chaseman spent 17 years leading Post-Newsweek Stations — now Graham Media Group — after rising through the broadcasting ranks from news to program syndication, serving as president of the Westinghouse Television Station Group until 1973, when he left New York to take the same title at Post-Newsweek.

During his time with the company’s broadcasting arm, which included four television stations, he led policy and development.

In a memoir by Katharine Graham, she wrote that during Chaseman’s tenure with the company, the stations’ operating margins “grew competitive with the best in the business.”

“Joel was the man who built Post-Newsweek Stations (now Graham Media Group) over more than a decade,” Graham’s son and successor as publisher, Donald E. Graham, wrote in an email to the Washington Post. “He started the company on its path to news leadership. He was a trusted adviser to Katharine Graham and a key director of her company.”

Chaseman, who was born in Trenton, New Jersey on Feb. 18, 1926, grew up in Albany, New York, and went on to serve as a Navy radar technician in World War II. He then graduated from Cornell University in 1948 and became an announcer at radio stations in Elmira, New York, and at a TV station in Baltimore.

Later accomplishments include serving as general manager for the company that produced “The Steve Allen Show,” among others, and serving as general manager of WINS, a New York station that was owned by Westinghouse that had gone to an all-news format in 1965.

In 1990, Chaseman left The Post and became a media consultant. He started an investment firm for ventures that included communications, marketing and fine arts.

He served as chairman of the Advanced Television Test Center and the National Academy of Television Arts and Sciences. Chaseman won several professional honors, was involved in multiple industry organizations and was a champion poker player.

In addition to his daughter, of Montclair, N.J., survivors include another daughter, Martha Chaseman of Washington; a brother; and two grandchildren, according to The Washington Post.

Chaseman is preceded in death by his wife of 58 years, Marlene Meyerson Chaseman, who died in 2014; and their son, Michael Chaseman, who died in 1975.
