Owner:: Mississippi Authority for Educational Television
History:: Came on the air in 1984 as the coastal affiliate of Public Radio in Mississippi.

In 2005 the radio and educational television divisions were re-branded as Mississippi Public Broadcasting.

The network garnered some notoriety in the summer of 2010 when it abruptly dropped the Fresh Air program after comic Louis CK talked openly about sex. It quietly re-added the program after the furor died down.

In July 2013 the station relegated all music programming to the HD-2 subchannel, leaving all news and talk on the main analog/HD-1 channel.

The station was granted a permit for an auxiliary site in late December 2022. The auxiliary is located on the same tower as the main antenna but at a lower height.

At the start of August 2023, the station increased its HD digital sideband power to 3.98 kW, or nearly 4% of the analog output. In September the station filed a license modification update to note they changed antenna types to a different brand, which necessitated changing the antenna height by one foot. A license to cover for that change was granted in April 2024.
