The most common example of this is the tobacco industry and it's pretty much still there. Smaller, sure.
But do we really regulate the sugar industry killing millions every day? Or the car industries destroying the environment, cities and people? Oil industry perhaps?
There are many other examples of these. They are "regulated" in the strict sense, but in reality, they control governments and keep doing whatever they want.
I don't think anything will ever change in this scenario. After all, capitalism is the answer to every problem, right? /s
