On 6 May 2010, more than half a million Facebook users voted in the UK election. We know this because they told us. Each of them pressed a button on their Facebook profile announcing they had exercised their electoral right. Their Facebook announcements almost certainly galvanised other people to vote and increased turnout. At least, we know that is what happened in the US election that November. Research on the US Facebook election experiment concluded that the “I voted” button motivated 60,000 voters to go to the polls in the US in 2010, and that in turn triggered 340,000 extra votes. Facebook’s intervention took it beyond a passive platform and towards having a more active civic role, but given the decline in voter turnout in the UK and US, few would argue that getting out the vote was not a civic good.
Facebook and other US digital media giants – Google, Twitter, Apple, Amazon and others – have already become integral across our work and social lives. Half of the people in Britain who use the internet are active Facebook users. Google has an 88 per cent share of search in the UK, and 92 per cent in Europe – and even higher in mobile search. Government ministers and departments now rely on Twitter to communicate policy. Eight out of ten ebooks sold in the UK are sold by Amazon.
