What should I minor in?

[thario_v1]

I plan on majoring in Marketing at the University of Houston starting in the Spring Semester in 2011. I want to minor in something to increase the value of my degree. Will that expand my career options? Give specific examples from experience if you can, as well as ideas for my minor.
what I enjoy about marketing is the promotional side, more along the lines of advertising, coming up with ways to sell a product or creating the actual ads, I dont want to major in advertising because I feel that may be too narrow of a degree.
