When I was younger I used to enjoy reading my grandmother's collection of Which magazines. This was way back in the sixties, when consumerism was just getting going. I still get the magazine today. It has turned into a bit more of a lifestyle publication than it used to be; when it is recommending tumble driers that cost more than five hundred pounds as "best buys" you just know that something has come adrift. It still has teeth though, as its latest investigation into the way that products are getting smaller but not cheaper illustrates.
However I think it had its heyday in the fifties and sixties, when there were many such issues to address. They also had a way with graphical design which was quite ahead of its time. Take a look at these covers for a glimpse of history.
