What is Asset Management Marketing?

Hello!

I am interested in learning more about this field in particular, within the context of Asset Management. No one at my university has gone into this in particular (people go into IB mostly), and I've seen it as an option within JP Morgan's Asset Management application. If anyone has done Asset Management marketing, at JP Morgan or anywhere else, if you could let me know more about what you have done during the course of your time there, I would truly appreciate it. Also any tips for preparing for interviews/ links to sites that could give me more information. What I've found online so far has been very general.
