4oD

That's texting-talk for (Channel) 4 on Demand...
4oD is Channel 4's new video on demand service. This has been around for a few months now, but now it just got bigger & better. Or so they say:

You may have noticed there's been some changes to make 4oD even better. From now on, you can catch up on most of the last week's TV for free, with around 80 hours of new shows available to watch online every week. From Hollyoaks to Wedding Belles and, coming soon, brand new Peep Show, there will always be top free TV on 4oD. We're also introducing a brand new 'Watch now' option so you can watch any free catch-up programmes online as soon as they're made available.

Sorry. Only available in the UK & Eire.
