Where does the name of the popular clothing store 'Gap' come from?

MONTAGNE: The Gap's co-founder, Don Fisher's wife, Doris, came up with the name The Gap. And I gather it was in reference to generation gap that was so much talked about then.

The retailer took its name in homage to "the generation gap," a term popular in the late 1960s describing the intellectual, ethical, and social gulf between young people and their parents' generation. The inspiration for this first jeans-only store came from Donald Fisher's frustrations as a consumer: he was finding jeans hard to shop for, having to travel to several different stores to examine a variety of brands because no one location housed them all.
