E4 Extra shows comedy and entertainment programming, along with repeats of some Channel 4 programmes. It had broadcast music programming in the mornings until April 2023.[3]
Idents for the new channel have been directed by Michael Marczewski, where various everyday events develop unexpectedly, such as 'most dangerous interdimensional monster' being entered alongside a village fete's massive vegetable competition.[4]
On 27 September 2022, E4 Extra moved from 139 to 138 on Sky, following the transition of Channel 4 HD from a single nationwide service on 138 to a fully regionalised version at channel 104 (108 in Wales, where S4C occupies 104). 139 was subsequently used by Sky Sci-Fi.
