Pfizer laboratories accidently created the market for sex enhancement pills in the 1990’s. While working with an experimental drug to reduce blood pressure, men participating in clinical trials began having erections. The 1998 by-product of this discovery ushered in a modern day sexual revolution. Prescription drugs for erectile dysfunction were an overnight success and have since become a multi-billion-dollar business. One can’t live in the modern world and not be acutely aware of the little blue pill that changed the world, Viagra.
