eli5: Why do some pills come loose in a bottle like Tylenol, while others are in separate pouches?

Question

Why do some pills, like Tylenol, come in a loose form inside a bottle, while others are individually packaged in separate pouches?

Is this because some pills are more abused/misused? Does size play a factor? Small Pill = Different packaging.

As others said, regulation. And also to note that blister packs are relatively more expensive so manufacturers may default to bottles where they can.
