WTMJ inaugurated the "Today's TMJ4" brand on July 25, 1992, coinciding with the start of NBC's coverage of that year's Summer Olympics (variants of this brand, whether they incorporated the last three letters of the callsign or not, were later used by other stations such as KTHV in Little Rock and WTMJ sister station KIVI-TV in Boise). The first generation of the "TMJ4" branding lasted until August 13, 2004, on the date NBC began its coverage of the 2004 Summer Olympics, as part of a graphical overhaul that resulted in the retirement of the "sailboat 4" logo that had been in use by the station since 1980. The "Today's" part of the branding was dropped on February 25, 2020 as part of a corporate roll-out of new news graphics.
