Keep an eye out for Phorm which BT, talk talk and Virgin have signed a contract with.
Three of the UK's biggest internet service providers have made a move to grab a share of the booming online advertising market through a new deal that allows them to help serve targeted adverts to their customers.
BT, Virgin Media and Talk Talk have signed exclusive deals with advertising technology company Phorm to use its Open Internet Exchange service.
OIX monitors every website that a customer visits and sends this data back to a central advertising hub.
Relevant ads are then served up to users, replacing more generic display advertising.
Talk talk have agreed that their customers have to opt-in but it seems likely that BT & Virgin will have an opt-out agreement.
I am just posting this for reference in case you do NOT want your ISP monitoring your every move. I will certainly be going for the opt-out option on Virgin.
