KateModern, Bebo's interactive drama (don't you love the way that soap opera on the net is still spoken of as if it's a new idea, about a decade after The Spot?) has done a deal which will see Atlantic Records' second division hoofers The Days pop up in the story:
It's not actually blurring fiction and reality any more than those bits of The Archers where they drop in a rapidly-recorded scene featuring whichever actors were available discussing the latest agricultural disaster from the headlines does. Much as we love those moments - like the bit where Lilian Bellamy had to pretend to be interested in some cow-threatening plague because, presumably, they couldn't find an actor who played an actual farmer to get to the studios at short notice - they don't actual make us think "it's so realistic", but, because you start to ruminate on the process which made a bit on bluetongue or hoof-and-mouth appear at such short notice, they underline the unreality.
Now, if The Days didn't know they were appearing as a paid-for advertisement in a made-up story... now, that might blur the boundaries a bit.
