If you haven't seen PBS Idea Channel with Mike Rugnetta, you are missing out: in each video, he examines something different from popular culture, from what Too Many Cooks means to Orphan Black as an illustration of simulacrum to how Ms. Marvel is changing media for the better. And since Valentine's Day is coming up, they decided to do a video dedicated to shipping, with the emphasis on one ship in particular: Korrasami.
The video examines the relationship between the fans of shows, the writers of fanfiction, and the shows themselves. Interestingly, Rugnetta lists off a number of slash ships...including Peggy Carter/Angie Martinelli.
Go watch it.
