Launched in June 2004 as B4 TV by CSC Media Group, Flava broadcast hip-hop, urban, and R&B music from the late 1970s to the 2010s.

Flava launched on 12 July 2004 as a test channel named B4, focusing on pop and dance music.

It played pre-release music videos and allowed viewers to request songs.

The rebranding of B4 to Flava was indicated by a change in the Ofcom license and program guide references by early March 2008.

On 23 April 2017, Flava introduced a new logo and updated its graphics, changing from blue to black, with red and yellow accents.
