The move quickly paid off; in 1982, it overtook WBTV for the lead at 11 p.m., a lead it held for almost 25 years. It surpassed WBTV in most other timeslots beginning in 1990, but lost the lead in the noon time period to WBTV in 1994. Channel 9's two-decade dominance of the early evening news timeslots largely stemmed from the former presence of "Oprah" as a lead-in to the 5:00 p.m. newscast; the syndicated talk show aired on channel 9 throughout its national run from 1986 to 2011. During the February 2011 ratings period, the station's newscasts won in every time slot except noon and 11 p.m., which were won by WBTV. WSOC-TV lost the lead at noon as well in the February 2013 sweeps period. By the February 2016 sweeps, however, the departure of a number of key reporters in 2015 resulted in WSOC-TV falling to second place in all timeslots. However, it maintained its historic dominance east of the Catawba River. Since 2000, WSOC-TV has produced a 10 p.m. newscast for sister station WAXN-TV. The program originated on then-Fox affiliate WCCB through a news share agreement established with that station in 1999, until the summer of 1999, when WCNC took over production of the primetime newscast shortly before WCCB launched its own news department in January 2000. During the February 2011 ratings period, WSOC's 10 p.m. newscast on WAXN placed second behind WCCB's in-house newscast; it also placed ahead of the WBTV-produced newscast on then-CW affiliate WJZY (channel 46, now a Fox owned-and-operated station), as well as the 11 p.m. newscast on WCNC. Bill Walker served as WSOC's main anchor from 1971 until his retirement in 2005, the longest tenure of any news anchor in Charlotte television history. On April 22, 2007, WSOC-TV became the first television station in the Charlotte market and the second station in North Carolina overall (after Raleigh CBS affiliate WRAL-TV) to begin broadcasting its local newscasts in high definition (WSOC was also the fourth Cox-owned station to upgrade its newscasts to HD, following WSB-TV and Orlando's WFTV); the WAXN broadcasts were not included in the upgrade until October 2008.
