All 4 relaunches with ad-free option and iOS app Details Editor | 01 March 2019 UK broadcaster Channel 4 has relaunched its popular All 4 video-on-demand (VOD) service with a new visual identity, a new iOS app and an invitation for selected registered users to trial a paid-for ad-free upgrade. The relaunch comes after 2018 became the most successful year for All 4 since it launched in 2006, with views up 25% year-on-year. The Walter Presents non-English drama also had its best year ever on All 4, surpassing 27 million views with programmes such as 13 Commandments and Killer By The Lake. Perhaps the most interesting of the upgrades is All 4 + which runs programmes without ads in commissioned content. The option was launched as a small-scale test in late 2018 and Channel 4 says that it is now being taken to the next stage. More registered users will be invited to trial paying to watch commissioned content without ads and the results will inform decisions about extending this service over the coming months.
