That's per a five-year amendment to Charter's five-year cable TV renewal license. Selectmen approved the amendment Monday night.
The deal includes fiberoptic drops at those three sites, Cable Access Television Director Kathy Dalgleish told selectmen.
Charter also will provide Northborough with a $85,000 capital grant, and increase "the operational funding from 3 percent to 4 percent of their gross to support the public educational and government channels," she said.
The Charter and Verizon licenses now are "closer in alignment," and both now expire in 2,018, "making renegotiations of future contracts much easier," Dalgleish said.
