Big Three networks. On September 14, 2006, Tribune Broadcasting sold CW affiliate WLVI-TV (channel 56) to Sunbeam Television for $117.3 million. The sale was approved by the FCC in late November of that year, creating Boston's second television duopoly (the other one being WBZ-TV and WSBK-TV, channel 38). WLVI moved its operations from its Dorchester studios to WHDH's facilities in downtown Boston. On April 2, 2009, WHDH announced that it would not air The Jay Leno Show, when it debuted on NBC in September 2009, electing to replace it with a simulcast of the 10:00 p.m. newscast that WHDH began producing for WLVI in order to better compete with Fox affiliate WFXT. The network quickly dismissed any move of Leno to any time slot other than 10:00 p.m., stating that WHDH's plan was a "flagrant" violation of the station's contract with the network and that it would consider moving the NBC affiliation to another Boston area station, either by creating an owned-and-operated station through an "existing broadcast license" in the market owned by NBC or by seeking inquiries from other stations in the market to acquire the affiliation. WHDH began removing all references to the proposed 10:00 p.m. newscast from its website the next day, and on April 13, 2009, the station announced that it had decided to comply and air The Jay Leno Show instead.

Other 'first-to-last' drops among NBC affiliates' newscasts in the 11:00 p.m. slot and overall affiliate pressure forced the network on January 10, 2010, to pull Leno from 10:00 p.m. starting after the 2010 Winter Olympics and move him back to The Tonight Show in a controversial shake-up of its late night schedule. Although the radio station had dropped the WHDH callsign in 1994, channel 7 retained the "-TV" suffix in its call letters until July 8, 2010. Loss of NBC affiliation It was reported on August 31, 2015, that NBC Owned Television Stations was considering the possibility of purchasing WHDH; NBCUniversal already had a strong presence in the market through its ownership of New England Cable News (NECN), CSN New England, and Telemundo station WNEU (channel 60), while
