I just remember reading The Stars My Destination from Bester and noticing all these elements:

* Mega-corporations with immense power and influence over all of society (Kodak of Kodak)

* Drug dens offering synthetic designer drugs that made people feel as if they were various animals.

* The protagonist receiving an upgrade to his nervous system, including a tooth-based switch that allowed him to 'speed up' for brief periods.

* Status symbols of the ultra-rich, such as using the most elaborate physical conveyances in an era of effortless teleportation.

I'm probably missing some, but it felt like such a prototype novel to something like Neuromancer and was written in 1956!
