December 12, 2011, CBS Television Stations announced its intent to purchase WLNY-TV, creating a duopoly with the CBS network's flagship station WCBS-TV. Terms of the purchase were originally not made public, though an FCC application for the purchase later revealed that CBS had purchased WLNY for $55 million. The company announced that it would add additional on-air staff and expand WLNY's local news programming outside the 11 p.m. newscast that the station had at the time. The FCC approved the sale, and CBS took control of the station on June 29, 2012, giving the company its tenth television station duopoly—as well as its largest duopoly by market size. The sale to CBS did not include repeaters WLNY-CD (channel 45) in Mineola, New York, WLIG-LD (channel 17) in Morristown, New Jersey, and W27CD in Stamford, Connecticut, which were sold separately to Local Media TV Holdings, LLC. On March 12, 2012, WLNY-CD changed its call letters to WMUN-CD and WLIG-LD changed its call letters to WNMF-LD; the WLIG-LP call letters then moved to W17CR, a station in Plainview, New York, that WLNY acquired on November 28, 2011, in a deal originally reached in 2005 and was not involved in the sale of either WLNY-TV or the other repeaters. On March 29, 2012, the day before the completion of WLNY-TV's sale to CBS, WMUN-CD, WNMF-LD and W27CD signed off temporarily in advance of the completion of their sale to Local Media TV Holdings on April 3, due to the end of the feed from WLNY's Melville studios. In early July 2018, WLNY-TV completed its move to UHF channel 27 under special temporary authority; the station then moved to UHF channel 29 in early August 2019 in phase 4 of the spectrum repack. On December 4, 2019, CBS Corporation and Viacom remerged into ViacomCBS (now Paramount Global). A January 2021 investigation by the Los Angeles Times based on complaints to the Pennsylvania Human Relations Commission revealed that, as part of the 2011 transaction by which Pascucci sold WLNY-TV to CBS, Peter Dunn, the head of CBS Television Stations, gained the use of a CBS-paid membership to the exclusive Sebonack Golf Club in Southampton, which Pascucci owns and which gave Dunn connections to billionaires such as fellow member Stephen Ross. Dunn was revealed to have treated this membership as a personal perk of the sale; per the Los Angeles Times, a colleague, CBS Entertainment Group
