Steiner Studios opened along the Brooklyn waterfront in 2004 as the largest film studio outside Hollywood. Television and movie productions had fled New York City for cheaper locations, and the new studio was trying to ignite a turnaround.

Nearly 15 years later, the industry has exploded.

Steiner, which started with five sound stages and one movie in production, now has 30 stages, a back lot about to start construction and multiple shows and movies filming simultaneously. In Queens, Silvercup Studios has added two new production outposts , including one in the Bronx.

And several weeks ago, Netflix announced a significant expansion in New York, creating a new corporate office in Manhattan and a production hub in Brooklyn with sound stages to feed its booming streaming service.

Now the actor Robert De Niro is jumping on board. A group of investors, including Mr. De Niro and his son, Raphael, are buying a five-acre parcel in Astoria, Queens, with plans to build a sprawling production and film studio.
