The chief marketing executive at Motorola has made a sudden departure, the Wall Street Journal has revealed in a report. Brought to the company in October 2006, Kenneth Keller Jr. has largely been responsible for the latter half of the company's promotional campaign behind the RAZR and is known to have perpetuated the theme across most of the company's lineup, including the RAZR2 and spinoffs such as the ROKR line. No reason has been given for his departure, which remains unannounced by the company.

The news comes after the company has suffered numerous critical defeats related to its mobile business, which included a 38 percent drop in phone sales at the end of 2007 as well as the departure of chief Ed Zander, who is often credited as shepherding the original RAZR to its rampant early success. Several other officials have left in past months, including mobile head Ron Garriques, who now works for Dell.
