Bosses of the hit CBS network show planned to move filming to the Canadian area, which often serves as a cost-effective stand-in for New York, after learning the city and state's film tax credit had expired.
The show's relocation was predicted to cost millions and result in the loss of 600 to 1,000 jobs.
State Assembly Speaker Shelly Silver moved quickly to win over CBS CEO Les Moonves in a bid to halt the move, promising the mayor's office, Governor David Paterson and the state Legislature would ensure Blue Bloods would get its tax credit, which would be retroactive to the start of production.
According to the New York Daily News, Silver's plight was successful.
She says: "When the mayor asked, I was glad to make the call. New York wouldn't be New York without our film and television industry, and I am deeply committed to keeping it here."
A spokesman for Moonves did not respond to request for comment.
