After news broke of singer Amy Winehouse's death, an Xbox-branded Twitter feed (@tweetbox360) sent out one of the most insipid messages of the year. Capitalizing on events is nothing new in the corporate world, but Microsoft's gaffe was exceptionally stupid. The company later told followers it never meant to come across as "commercially motivated." Funny, you could have fooled us. Then again, sales of Winehouse's Back to Black did skyrocket after her death, so maybe grief really has gone commercial.
