The rebrand is nearly complete. Last year, Channel 4 announced its 4oD catch-up and on-demand service would relaunch as All 4 before the end of March. And true to its word, it will happen on Monday.
The website and iOS app will update to the new branding, and include new features.
The Android app will work as it does now without the new extras, but feature the All 4 logo instead. It's expected to catch up later in the year, along with other digital platforms.
So, the new sections then. On Demand features classic shows like 'Shameless' and 'Father Ted', many of them in their entirety.
The 'Now' category is where you'll find what's airing at the moment. And you can head to the 'Soon' section to see previews of what's coming up.
Old shows will be given fresh extras, such as cast interviews and galleries. You'll also be able to watch the shows in the Now section live, and enjoy news clips, short videos and social media 'banter'.
Worried you'll miss your favourite show? The On Soon section lets you set a reminder. Some episodes will premiere in the section before they're shown on regular TV.
O2 customers will be able to see certain shows 48 hours earlier than anyone else, as part of the network's O2 Priority scheme.
These shows include 'Fresh Meat', 'Peep Show' and 'Made in Chelsea'. The deal will last until the end of the year.
