The one video everyone should see about SOPA is this one by Clay Shirky.
And if you think SOPA is going away, think again. It will change its name and be back again. In fact, the controversial ACTA treaty, which has similar goals to SOPA, is already marching toward becoming law. ACTA stands for "Anti-Counterfeiting Trade Agreement" but it is largely focused on policing the internet and punishing individual internet users. ACTA is arguably worse than SOPA, and was known among activists even before SOPA, although the text of the treaty has been kept secret from the public until recently. The fight between citizens and Big Copyright is one that we will have to keep fighting--right now, and for a long time to come.
