Asking what you asked, is the equivalent of me asking this:
"Which is longer, a piece of string or a piece of rope?"
All of those things are capable of making money. All of those things are also capable of not ever making you a dime.
It's the implementation that creates monetization.
To further answer your question, anytime you ever make money on the internet, that ALL falls into the category of "IM" (internet marketing).
For instance, if you were to make $1.50 because somebody submitted their email address to one of your CPA landers, they got there because you marketed that page in such a way as to get a visitor to it....hence "internet marketing".
