WCBI-DT2 is the MyNetworkTV-affiliated television station for Northern Mississippi and Northwestern Alabama. The station is a second digital subchannel of CBS affiliate WCBI-TV owned by Morris Multimedia. Over-the-air, it broadcasts a standard definition digital signal on UHF channel 35.2 (or virtual channel 4.2 via PSIP) from a transmitter in Northwestern Clay County. Known on-air as My MS, this can also be seen on Comcast channel 3 and Cable One channel 4. Syndicated programming on WCBI-DT2 includes Family Guy, How I Met Your Mother, Everybody Hates Chris, and 30 Rock among others.
After WCBI signed-on its digital signal in August 2002, it launched this second subchannel to be the market's UPN affiliate in early-September. WCBI-DT2 was known on-air as "UPN Mississippi" and was one of the first digital affiliates of the network in the country. On January 24, 2006, UPN and The WB announced the two networks would cease broadcasting and merge, forming a new network called The CW; on February 22, News Corporation announced it would start up another network called MyNetworkTV. On September 5, WCBI-DT2 became part of MyNetworkTV and was branded as "My MS".
On September 8, 2008, WCBI began producing the area's second prime time newscast on this station. Known as WCBI News at 9 on My MS, the broadcast only airs on weeknights for thirty minutes and competes with another prime time show seen for a half-hour on Fox affiliate WLOV-TV (produced Sunday through Friday nights by NBC affiliate WTVA). At some point in time, WCBI added an hour-long extension of its weekday morning show to this station. Known as WCBI News Sunrise on My MS, this broadcast can be seen from 7 until 8 and offers a local alternative to the national network morning shows. In addition to its main studios, the station operates a Tupelo Bureau on Main Street/U.S. 278/MS 6/MS 178. On September 16, 2013, both newscasts on WCBI-DT2 moved to WCBI's third digital subchannel that has CW affiliation.
