This is a good video by Luke Smith: "Social Media as Social Control."

"Whether planned or not, Social Media's prime current function is behavioral engineering at a massive scale. Most sites function as massive Skinner's Boxes, conditioning users to behaviors desired by those who run the sites. Part of this is inevitable, but it has certainly accelerated in recent years and will continue so long as people continue to rely on such sites."

The video is 15 minutes long.
