History
WEIU-TV began operations on July 1, 1986, as an independent non-commercial station offering public affairs and instructional programming, as well as the student-run news program News Scan. On January 30, 1992, WEIU-TV officially joined PBS. In January 2002, the newscast was renamed News Watch; it currently airs from 5:30 p.m. to 6:00 p.m. News Watch won its first Emmy Award in 2009 and its second Emmy in 2010.

WEIU-TV launched its first digital broadcast in 2006, on UHF channel 50 (tuned as virtual channel 51). The station began broadcasting in high definition (HD) on March 22, 2010. It offered the first local HD newscast for viewers in central Illinois. Before June 2010, no commercial television stations in the market were producing news in HD, which changed when NBC affiliate WAND became the first to make the switch.

Digital channels
The station's digital signal is multiplexed:

Analog-to-digital conversion
On February 17, 2009, WEIU-TV shut down its analog signal over UHF channel 51. This was the original target date on which full-power television stations in the United States were federally mandated to transition from analog to digital broadcasts. The station's digital signal remained on its pre-transition UHF channel 50. Through the use of PSIP, digital television receivers continued to display the station's virtual channel as its former UHF analog channel 51.

Related channels
In addition to its main station, WEIU-TV also operates "Your 13", a cable TV channel offered to Consolidated Communications subscribers that presents educational, sports, informational and local public access programming, as well as an overnight simulcast of WEIU-FM. Unlike WEIU-TV, some of the programs on "Your 13" are funded by commercials.

WEIU-TV also broadcasts a variety of international programming on its second digital sub-channel.
