Blame BT (British Telecom) They introduced an ad service called phorm (without asking anyones permission) it tracked all your online activity and then removed the regular ads from pages its ISP served and replaced them with ads that would be interesting to you based on your browsing history. It got into trouble when it removed ads for charities and placed porn ads in childrens sites. Because it worked at the ISP level, clearing your history or cookies had no effect. They then introduced a cookie to allow you to opt out and claimed that by deleting this cookie you had volunteered to opt in! The Eu investigation ruled that it broke wiretap laws but the UK refused to prosecute (BT is privatized but is almost a monopoly and has strong links to government)
