Can Fandom Change Society?

I came across this interesting video today from PBS:

On the whole, I found the concept to be pretty good, but their choices of fandoms to focus on made the whole thing seem weirder than it actually is. Bronies? Transformers slash fiction? Really? Did we need to focus on that so much? No mention of the thousands of hours of charity work that Trek fan organizations like Starfleet International do? Nothing about how television shows like Big Bang Theory and the wild success of Comicon have made fandom mainstream? 

I wish they had given a broader picture of fandom rather than pushing a very specific agenda.
