Consumer journalism is a staple of the UK media and its development over time provides an illuminating device for exploring the changing attitudes of UK shoppers.
Programmes have become more assertive, more knowing and more resourceful, from door-stepping to using elaborate sting operations and hidden cameras.
Likewise the suppliers have become wiser and more adept at dealing with the media.
Consumers have become better informed about the products they buy and their rights, but still we are repeatedly duped by the most crude of con tricks.
The programme examines how consumer journalism has changed over the years.
It includes archive material from people like the American consumer champion Ralph Nader in the sixties to more recent campaigners such as Ann Robinson and Esther Rantzen.
There are also fresh interviews with people recalling the early days of Which magazine and Good Housekeeping.
