WBTS-CD

WBTS-CD (channel 15, cable channel 10), branded NBC10 Boston, is a Class A television station licensed to Nashua, New Hampshire, United States. Serving as the NBC outlet for the Boston area, it is owned and operated by the network's NBC Owned Television Stations division. Under common ownership with Merrimack, New Hampshire–licensed Telemundo outlet WNEU (channel 60), regional cable news channel New England Cable News (NECN), and regional sports network NBC Sports Boston, all four outlets share studio facilities at the NBCU Boston Media Center on B Street in Needham, Massachusetts. WBTS-CD is broadcast by full-power WGBX-TV (channel 44) from its transmitter site on Cedar Street, also in Needham, giving it full coverage of the Boston television market. It is branded as channel 10 owing to its primary cable channel position.

The license started in Nashua on January 29, 1988, as W13BG "TV13 Nashua", a low-power community television station which later changed its call sign to WYCN-LP in 1996. Its programming consisted of local-service programming for the Nashua area and content already aired by local cable systems as well as, later on, FamilyNet. WYCN-LP and associated translators were sold to New Hampshire 1 Network, a company controlled by William H. Binnie, in 2010. Three years later, Binnie sold WYCN-LP to OTA Broadcasting, which removed remaining local content and converted the station to digital broadcasting.

OTA Broadcasting sold the spectrum underlying WYCN-CD in the FCC's 2017 incentive auction. Without a transmitter, the station arranged to share the transmitter of WGBX-TV, giving it full-power coverage in the Boston market. OTA Broadcasting then sold WYCN-CD to NBC, whose NBC Boston service had launched at the start of 2017 on several transmitters but lacked a single primary signal. The station changed call signs to WBTS-CD in 2019 in anticipation of the relocation of the former WBTS-LD license, now WYCN-LD, to serve the Providence, Rhode Island, area.

The station came to the air at 8 p.m. on January 29, 1988, as W13BG on VHF channel 13 in Nashua; its license was granted on July 29. Founded by Robert Rines and owned by Center Broadcasting Corporation of New Hampshire, a non-profit partnership between the Concord–based Franklin Pierce Law Center and the Boston–based Academy of Law Sciences, the station aired local community programming for the Nashua area, along with programming that was already being sold to cable stations though the Yankee Communications Network. Channel 13 changed its callsign to WYCN-LP on April 8, 1996. Its tower in the analog era of television was on the campus of Rivier University, between two above-ground reservoirs and Brassard Hall, with studios in Memorial Hall on the same campus.

WYCN-LP was nearly dropped by Harron Cable on its Nashua-area systems in October 1999 to accommodate a must-carry request by WMFP (channel 62), a move that could have led to the closure of channel 13 even though its carriage on MediaOne in Nashua itself was not affected. Its carriage was ultimately continued by Adelphia Communications following its purchase of Harron, though the station was dropped for a time in 2000 after an additional must-carry request, from WYDN (channel 48), while Adelphia rebuilt the systems. By August 11, 2000, WYCN-LP had been authorized to carry programming from FamilyNet.

WYCN-LP, along with three co-owned translators in Nashua, Manchester, and Concord, was sold by Center Broadcasting Corporation of New Hampshire to New Hampshire 1 Network, a company controlled by William H. Binnie, in 2010; by this point, control of the stations had passed to longtime WYCN staffers Gordon Jackson and Carolyn Choate following the death of Robert Rines. The deal was completed January 3, 2012; in the meantime, Binnie would also acquire WBIN-TV (channel 50, now WWJE-DT) in Derry. As a result of the sale, much of WYCN's community programming, including aldermatic debates, was discontinued. In December 2012, the station's studios moved from Rivier University to a location shared with sister station WFNQ (106.3 FM).

New Hampshire 1 Network filed to sell WYCN-LP to OTA Broadcasting, a company controlled by Michael Dell's MSD Capital, on January 14, 2013; the three translators were not included in the deal, and began to simulcast WBIN-TV. Operation of WYCN continued to be handled by New Hampshire 1. At the time of the sale, WYCN was affiliated with My Family TV. The Federal Communications Commission (FCC) approved the sale on March 22, and it was completed on May 20.

WYCN-LP resumed producing local programming soon after the sale to OTA Broadcasting, rehiring Gordon Jackson and Carolyn Choate as station managers; however, in June 2013, Comcast (successor to both Harron/Adelphia and MediaOne) informed the station that it would be dropped from its lineup as of August 15 due to the earlier cessation of local programming, as well as its limited broadcast reach and continued analog broadcasting, even though WYCN had a construction permit to convert to digital operations and increase its broadcast range. Comcast subsequently pushed back the date of the removal to September 3, despite protests from viewers, politicians, and Nashua's public access station.
