station of Imes' once-sizable smaller-market broadcasting group. The Commercial Dispatch remains under Imes family ownership to this day. On September 5, 2006, the UPN Mississippi subchannel was relaunched as "My Mississippi", affiliating with MyNetworkTV as part of the merger of UPN and The WB. Thirteen days later on September 18, the weather subchannel on DT3 was converted to a CW affiliate as "North Mississippi CW". News operation On September 8, 2008, WCBI began producing the area's second prime time newscast on this station called WCBI News at 9 on My MS. It 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 WCBI-DT2 titled WCBI News Sunrise on My MS, which airs 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/US 278/MS 6/MS 178. On September 16, 2013, both newscasts airing on WCBI-DT2 moved to CW affiliate WCBI-DT3. Technical information Subchannels The station's digital signal is multiplexed: Analog-to-digital conversion WCBI-TV shut down its analog signal, over VHF channel 4, on January 24, 2009, due to a transmitter problem. This was under a month before the original date of the federally-mandated transition from analog broadcasting to digital broadcasting (the original date was February 17; it would later get pushed back to June 12). The station's digital signal remained on its pre-transition UHF channel 35. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 4.
