Right, let's keep this simple. You've got your TV, and you've got your internet computer machine. But wait: you can watch TV over the internet, and you can watch internet things on the telly. Here's one of the latter: MySpaceTV.
MySpace has just signed a deal to broadcast its own programming on non-US television networks. Its most famous programe is a show called 'Quarterlife'. Never heard of it? You're not alone - in February the US network NBC gave it an airing and it performed miserably in ratings terms.
But if things work out, this might just change the way TV works. The old paradigm is that you commission a TV programme, spend loads of money on it and then hope people like the pilot, or the first series. If they don't, you've wasted a load of cash that could be spent on thick-rimmed spectacles and ironic haircuts.
(Alright, that's a gross simplification. But you get the idea - the process is a) spend money on programme, b) see if people like it.)
But if you stick a show on the web first, you can avoid a big chunk of marketing expenditure and avoid committing yourself advertising-wise in case people hate it. The whole pilot system that has dominated US television for decades could disappear forever.
Travis Katz, head of MySpace's international arm, explained the concept thus: "MySpace is essentially the world's largest focus group. You can see what resonates with people and then take that content and blow it out worldwide."
The only problem so far is that the basic material being shown on websites is of a generally poor standard - okay, that's a big problem. But if the paradigm (sorry) really is shifting, so will the talent - and who knows where the thing will end. Don't be surprised if the next thing you see on the Beeb is a TV dramatisation of David Price's PC Advisor blogs. You heard it here first.
