Sony: -16%
Sony spent $1.6 billion on advertising last year, according to Advertising Age magazine, but it wasn't enough to stem Sony's slide in global brand value. Its drop of 16% is all the more troubling as rival Samsung passed the Japanese giant in brand value while spending far less on ads.
According to Interbrand's Jan Lindemann, who directed the ranking, Sony's brand value has dropped because it gave up leadership in MP3 players to Apple by not innovating and because it hasn't been a player in cell phones. Another minus: Sony has devoted considerable resources to its film and music recording businesses, where its brand carries little weight with consumers.
