Discovery Communications will lay off more than 200 workers in its downtown Silver Spring office, according to several reports citing a state workforce adjustment filing.

First reported by the Washington Business Journal, the move will affect 212 workers, effective Oct. 1, as the company prepares to relocate its headquarters to New York City and sell the Silver Spring building.

The sale was announced in January, and a July report in the Washington Business Journal, said locally based Foulger-Pratt Co. and Rubenstein Partners, a Philadelphia company, were the finalists bidding for the property.

In June, the company announced its new headquarters would be located in leased space at 230 Park Ave. South in Manhattan.

The company agreed to move to the Silver Spring location in October, 1998 and the building opened in the spring of 2003.

John Hendricks founded the company in 1985 as Discovery Channel. The company continues to operate Discovery ChannelAnimal PlanetInvestigation DiscoveryScienceTLC, and other brands.

Hendricks later founded CuriosityStream, a service offering streaming documentaries that’s also based in Silver Spring, and serves as its executive chairman.
