Gerber Singles was a failed product from 1974 by Gerber, a maker of baby food. It was food in glass jars targeted to college students and adults living on their own for the first time.
[Supplement from mental_floss]: At some point in time, almost every adult has tasted baby food and discovered that the stuff isn’t half bad. But that doesn’t mean people want to make a meal out of it. For some reason, Gerber had to learn that lesson the hard way. In 1974, the company released Gerber Singles, small servings of food meant for single adults, packaged in jars that were almost identical to those used for baby food. It didn’t take long for Gerber execs to figure out that most consumers, unless they were less than a year old, couldn’t get used to eating a pureed meal out of a jar—particularly one depressingly labeled “Singles.” Baby food for grown-ups was pulled from the marketplace shortly after.
