Google is the world’s top brand, U.K. consultant Millward Brown proclaimed in a study released Monday. The ranking is based on strength of the firm’s name and image rather than stock value or revenue generated by the brand. Does this metric remind anyone of the eyeball and mindshare measures of the Internet bubble? Google is a strong brand, but tops in the world ahead of Coke and Microsoft seems a stretch. BusinessWeek’s survey last year ranked Google number 24 on its top brand list. This ranking is based on the more sober net present value of earnings the brand is expected to generate in the year ended June 30, 2006.
