The UK's Channel 4 is no stranger to on-demandprogramming, and now it's bringing the convenience of offline viewing to the mobile version of 4oD. In the latest update for Android and iOS, registered users can download shows that aired during the past 30 days, all for free. From there, users have seven days to view the content before it expires. There's a subtle catch, as all programming must be downloaded over WiFi, from within the UK or the Republic of Ireland. Once downloaded, however, shows can be watched offline from anywhere. Offline viewing is currently restricted to the network's commissioned shows, but it's looking to add programming from other studios in the future. Consider this Channel 4's way of keeping up with the Joneses... or in this case, the BBC.
