Simply put, three of the UK’s largest ISPs (Virgin Media, BT and TalkTalk) have decided to sell your private browsing history to an advertising broker. Yes, the entire list of every web page you visit gets sent to Phorm (the broker) in real time, as you click, so they can send you ‘targeted advertising’. Naturally the ISP’s are not too keen on telling their users this, they’d much rather feed us all platitudes about how it’ll help combat phishing and how the targeted adverts will be so much better than the random ones we see today.
