I'm interested in the way the whole cultural landscape can shift over time. Okay, this will seem like a silly example, but look at the whole discourse around "selling out," a concept people say is irrelevant because there's no more distinction between mainstream and underground, inside and outside (which I don't really believe, but that's another issue).

My point, though, is that if lines have indeed shifted, it's not so much that the younger generation just doesn't care, it's that we have ceded more and more of our public life over to the private sector. If you grow up with advertising at school, you have come of age in a sold-out world.

It wasn't that people wanted things for free and asked for advertising to fund it - it's that these companies wanted to amass an audience whose "eyeballs" they could sell, and they gave people things for free to do that. Free services and content has been foisted upon us because there wasn't the will power to explore other options.

I think that overall, ultimately the impact of advertisers calling the shots is a more cloying, complacent culture. For example, it was just announced that Unilever is branding environmental content at The Guardian. How radical or pointed can that content be?

To go from the vision that we would all be free to express ourselves creatively because our material needs were being met, to this reality where nobody has money, people are unemployed, and the machines are harnessed by the lucky guys who Facebook or Google and we're supposed to be happy just to contribute content to their site.

We've been criticizing these superficial aspects, like whether we are all more distracted. We really need to articulate a defense, a critique, that merges awareness of the technology with a more traditional, progressive, left-wing critique of the market.

Advertisers are happy to see the stuff they've branded out there for free, they don't care about scarcity, they want any message they're invested in to be shared and to be abundant and to be passed along.
