McDonald’s is one of the leading advertisers in the world,  spending about $2.5 BILLION globally each year (with more than half of that amount in the United States). As such, it is very demanding.

According to Advertising Age:

“McDonald’s is now searching for one agency to handle its U.S. creative work, a major shift from relying on two agencies for the bulk of its national advertising. It is the latest marketing shakeup at the world’s largest restaurant chain, where pitches have evolved quite a bit since the 1960 jingle “Look For the Golden Arches” and the 1963 debut of Ronald McDonald (then played by Willard Scott). Here’s a quick look back at some big advertising changes at the Golden Arches over the past two decades.”
