Available for over a year

New methods that collect your data to specifically target you: how far are they going? We speak to Kirsten Bay from Attensity which looks at the opinions behind the social media number and to Edwina Dunn and Clive Humby who are looking to help firms use data from social networks to expand their client base. Plus Professor Ryan Calo from the University of Washington tells us it's not so much about privacy and that instead we should worry about what profit-seeking corporations will do in the future to get people to part with their money.
