Channel 4 basically pioneered online catch-up services when it launched 4oD for PCs eight years ago. Since then, 4oD has evolved and improved, most recently adding offline viewing for mobile devices and the ability to stream over 3G and 4G networks. Back in May, however, Channel 4 CEO David Abraham teased a "significant upgrade" to the service -- incidentally, the BBC pushed its iPlayer redesign out around the same time -- and today we're learning more about what that will entail. For starters, 4oD will be renamed "All 4" to reflect its comprehensive nature, with a new logo for good measure. It'll incorporate all the live channel feeds, on-demand content and Channel 4 shorts you can already find on 4oD, but packaged in a brand new user interface.
