I wonder what the author is using to judge whether this was a successful campaign or not. Although his being off by two orders of magnitude certainly doesn't help. At the company I'm working for, we did a campaign for Keith Urban and it did pretty well, better than our (and clients') expectations. We built an application where for one week, we released 1 song a day. To get access to the application, you had to Like it.. and to listen to the song, you had to Like that too. He gained 60K additional fans from Likes (from a little over 1 mil fans) over 10 days or so, and albums sold were 150% above forecasts.
