Channel 4 almost had their own radio station

As in their own line of radio stations, following the acquisition of 51% of DAB radio station Oneword in October 2005 and launch of their radio station Channel 4 Radio in January 2007 but after winning the licence to operate the second national DAB radio multiplex in July 2007, they aborted plans after selling their stake of Oneword in December of the same year that led to its closure the following month and shutting down Channel 4 Radio on October 14, 2008, so here's eight of the proposed stations.

E4 Radio

Pure4

Talk Radio (not to be confused with Talksport's sister station, hence the logo in question is a generic logo)

Closer (based on the magazine)

Sky News Radio (spinoff to the Sky TV channel that would've been the expansion of the radio arm as well as LBC being rebranded under the name but LBC owner Global Radio pulled out due to financial reasons)

Sunrise Radio UK (national version of the British Asian oriented London radio station, which eventually happened in 2016)

Original (which would've been under Canadian company Canwest, owners of Global Television Network at the time, logo here is a generic one)

Radio Disney (serving as a de facto successor to Capital Disney)
