Twitter: Promoted Trending Topic with Toy Story 3

I don’t think Toy Story 3 needed help to be a top trending topic on Twitter, but apparently it pays to insure that it is:

Promoted Twitter Trend Topic - Toy Story 3
Promoted Twitter Trend Topic - Toy Story 3

I had assumed an advertising model was going to run through eventually, but I hadn’t thought about promoted trending topics.  Makes sense.  I wonder if it costs more to also include #toystory3 hashtag as a bonus?
