Is there different categories of marketing?

Are there sub sections of marketing? Like tactic marketing (small tiny "tricks") For example at some bars they sell 50 dollar shots of their best alcohol and they do that because most people wont buy the 50 dollars shot but instead buy the 20 dollars shot.



On the other side, on a much broader scale of things the more common marketing. Advertising, internet marketing..



Im also curious if anyone else knows of the "tactic marketing" and where I can find research on it and what it is officially called.
