Channel 4 killed off 4oD and replaced it with the new, All 4 on-demand service early last year. Since then, All 4 has made its way onto several important TV-connected devices and brought live streaming to mobiles and tablets. Next up: A visual upgrade. Not too much will change when the new UI comes to big screens like smart TVs, set-top boxes and consoles within the next few weeks, before hitting iOS, Android and the web in due course. A new dark background and slightly rearranged card-like UI are among the changes, but Channel 4 is making a point of talking up the new home screen, which'll blend data-driven recommendations with hand-picked content from human curators.
