Seems Stern's Marketing Club does a nice job of laying out the different careers in marketing:
https://people.stern.nyu.edu/gma/prospectivestudentscareers.htm.
They have links for the following marketing careers:
Brand Management
Product Management
New Product Development
Business to Business Marketing
Advertising
Public Relations/Communications
Internet/Direct Marketing
Non-profit Marketing
Market Research
Out of curiosity, are there other websites for marketing that you all have used?
