of the three stations to each other (as well as the common affiliation with NBC), were occasionally marketed together as a result. Cox changed the stations' on-air appearances to match WPXI's look, despite WPXI changing its own look in 2004. WTOV still used WPXI's former look until October 2010, and WJAC-TV adopted WPXI's current design in October 2011. Over the Labor Day weekend of 2007, WPXI began relocating from its longtime studios at Television Hill in Pittsburgh's Fineview neighborhood after 50 years, to a new studio facility in the city's Summer Hill neighborhood near the Parkway North. The station's transmitter tower continues to be located in the Fineview neighborhood. WPXI began broadcasting its newscasts from the Summer Hill studio on October 6 beginning with the 6 p.m. newscast. In turn, it also became the first station in the Pittsburgh market to begin broadcasting its local newscasts in high definition. The station was criticized for technical glitches during the initial week of the new system run but worked through the issues and set the pace of technological advances for WTAE and KDKA to follow. With the switch to HD came a new set, created by FX Group and a new graphics package designed by Hothaus Creative. In mid-October 2008, WPXI, in collaboration with Cox's longtime partner Internet Broadcasting, launched a redesigned website. By early November 2008, the websites of all of Cox's stations east of the Mississippi River began using the new format pioneered by WPXI; the websites of the company's stations west of the Mississippi River followed suit a month later. In 2011, Cox Media Group's partnership with Internet Broadcasting was dissolved, and the Cox television stations relaunched their website operations in-house. WPXI's and WSOC-TV's websites remained under the stewardship of Internet Broadcasting until late January 2012, when they became the last two stations to have redesigned their websites to match the format of the in-house web operations of their sister stations. With Cox Media Group's February 23, 2013, sale of WJAC and WTOV (a sale which also included KFOX-TV in El Paso, Texas and KRXI and KAME-TV in Reno, Nevada) to the Sinclair Broadcast Group, owners of local Fox affiliate WPGH-TV and MyNetworkTV affiliate WPMY (which was completed on May 2), WPXI became Cox's only NBC-affiliated station until 2019 when the company acquired Northwest Broadcasting stations KYMA-DT in Yuma, Arizona, KIEM-TV in Eureka, California, KPVI-DT in Pocatello, Idaho, and
