Apparently, Earthlink's Advertising account has been very promiscuous over the past few years... switching agencies regularly. They are now on their 4th Ad Agency - and guess who? TBWA-Chiat-Day - Yes - Apple's own.
According to this AdWeek Online article:
"sources said was a centralization of ad duties resulting from the "alliance" earlier this year of Apple Computer and Earthlink."
Centralizing a $50 million account because of Earthlink's alliance with Apple? I didn't realize they were so close... I guess we should expect some Apple/Earthlink ads in the future.
