Taste of Home, a cooking magazine with the median age of readership around 60, has a circulation of 3.4 MILLION. (!!!) This blows my mind. For comparison's sake, V is 30,000 copies; This Old House is 1.2 million; Martha Stewart Living is 1.9 million, and things like Time and People have a circ around 3.5 to 4 million copies.
So there's this magazine primarily dealing in recipe exchanges that covers the canned soup/jello salad arena that ALSO has one of the top 15 circulations in America. It's impressive. As much as I'd like to think food habits have changed in America (with a wider variety of produce and known ingredients available everywhere, for starters), seeing these actual numbers show what the reality really is. Bottom line: people who cook at home like food that's convenient and simple to cook.
