Gap celebrates 40 years in business

San Francisco Thursday evening, on the eve of its 60th anniversary, Gap will celebrate its employees and customers by hosting a nationwide simultaneous acoustic concert in its more than 700 stores nationwide from 7 p.m. to 9 p.m. local times.

The chain will continue the celebration on Aug. 21, when, for the first time in New York Stock Exchange history, the trading floor community will “dress down” for business and wear Gap's new 1969 Premium Jeans line, named in honor of Gap's debut year.

Later in the day, Gap brand North America president Marka Hansen, along with board member Bob Fisher and fellow founding family members John Fisher and Bill Fisher will ring the NYSE’s closing bell remotely from the company's headquarters in San Francisco.
