From Jackie Huba’s Tour bits:
I was honored to meet one of the deans of public relations: Al Golin of GolinHarris. He began his PR career in 1951 and today his company has offices in 29 countries.
One ingredient of Al’s success has been having McDonald’s as a client for 50 years. In 1957, Al cold-called Ray Kroc, the legendary force behind McDonald’s. Kroc hired him and put the firm on a $500 monthly retainer. (I’m sure the retainer is a bit higher today.) It’s remarkable for anyone to have a client for 50 years.
