I've been looking through a lot of local newspaper microfilms in my free time lately. Just for fun, I tried pinpointing when a few retailers' identities changed; at least in print:
Last appearance of the old Kmart logo, December 16, 1990.
First appearance of the new Kmart logo, December 30, 1990.
Last appearance of the old A&P logo, February 4, 1976.
First appearance of the new A&P logo, February 11, 1976.
Also:
First appearance of the '60s Penneys logo, November 21, 1963.
First appearance of the modern JCPenney logo, August 2, 1971.
First appearance of the boxed Montgomery Ward logo, May 10, 1968.

Pinpointing logo changes
"The pale pastels which have been featured in most food stores during the past 20 years are no longer in tune with the mood of the 1970s."

Re: Pinpointing logo changes
A&P was already using the new logo in New York and New Jersey as early as 1975
