In 1998, the station moved its studios from the Washington University campus to the Dana Brown Communications Center in the Grand Center district. During the 2004 elections, KETC partnered with area NBC affiliate KSDK (channel 5) to provide St. Louisans with comprehensive and up-to-date local and national election results. This partnership was first utilized to simulcast a gubernatorial debate between Republican candidate Missouri Secretary of State Matt Blunt and Democratic candidate State Auditor Claire McCaskill. On election night (November 9), KSDK aired NBC's prime time election coverage with Tom Brokaw and Tim Russert as well as segments of local results. KETC, meanwhile, ran three hours of local election results hosted by KSDK anchors Mike Bush and Karen Foss. Viewers could also watch election results online on the websites of both stations. The successful KETC/KSDK partnership was used again in September 2005 when, along with radio partners KYKY (98.1 FM) and KEZK-FM (102.5 FM), a telethon for Hurricane Katrina relief was simulcast that raised more than $5 million. The telethon featured an appearance by Affton native John Goodman, who now calls New Orleans home and whose family went missing for a time during the storm's peak. Kennett native Sheryl Crow and her then fiancé Lance Armstrong urged viewers to call when they were interviewed by phone from the region. In May 2008, E! contracted with KETC to film two episodes of the cable network's weekly pop culture series The Soup at the KETC studios to accommodate host Joel McHale's filming of The Informant! in the St. Louis area.

On January 10, 2021, the station rebranded as Nine PBS, adopting the current PBS corporate logo.
