Today's Tesco

Writing in today's Spectator Rod Liddle points his readers towards an article on the power of the supermarkets on The Ecologist magazine's website.

By tracking what you buy through your Clubcard, Tesco creates for you a favourite products list (similar to a list of favourite websites). When you connect to Tesco.com there is the list of products you normally buy. A helpful short cut, or too much information about you? One woman contacted Tesco when she saw condoms on her favourites list: she was puzzled because she and her husband didn’t use them when they were having sex. Tesco knew her husband was having an affair before she did.

There is more good stuff on the same subject from the New Economics Foundation here.
