All 4
All 4 is a video on demand service from Channel Four Television Corporation. The service launched on 16 November 2006 as 4oD (shorthand for 4 on Demand). The service offers a variety of programmes recently shown on Channel 4, E4, More4 or from their archives. However some programmes and movies are not available due to rights issues.
The cable and IPTV versions are operated through an appropriate set-top box whilst the internet variant can be accessed via their website. All 4 generated around 215 million long-form video views on all platforms where it is available in the first half of 2011, making Channel 4 the biggest commercial UK broadcaster in the video on-demand market during the period.
On 30 March 2015, 4oD was merged into and renamed All 4.
