Arguably, we've moved beyond purely disciplinary societies and into what Deleuze and others called "Societies of Control". One of the arguments there is that while disciplinary societies tend to have centralized enforcement mechanisms and ways of normalizing subjects into one single type of ideal subject (the ideal student, prisoner, patient, etc.), in control societies, things like shifting levels of access and networks of enforcement in which we police each other and ourselves become more important. There's a great, very short article by Deleuze talking about it [1]. Nonetheless, getting folks started on things like Discipline and Punish would be nice.
