Channel 4 has launched a new VoD and catch-up service called All 4, which replaces 4oD and will be available on all connected devices, but initially only on PCs and iOS mobile devices. More than a simplre rebrand, All 4 introduces several new functions. Viewers can watch Channel 4 programmes live on the move for the first time via the 'Now' section. It also includes an 'On Soon' feature, which allows users to watch the premieres of their favourite programmes before they air on terrestrial TV. Reality show Made in Chelsea will be one of the series made available prior to broadcast when it returns for a ninth season in April. Channel 4's confirmed that original short films will be on the service too, alongside catch-up and archive content from E4, More 4, Film 4 and its flagship channel. All 4 will launch next week on PC, iPhones and iPads with an Android app set to arrive later this year. Mobile network O2 UK is the service's exclusive partner, providing early access to some All 4 content
