Realistic advantage of studying the communications field?

I’m currently a junior in high school beginning to narrow down my choices for colleges. I have an interest in the communications field, particularly advertising, marketing, etc., but I’m not 100% confident that a degree in communications (whether general communications or something more specific) is really advantageous in the “real world.” Additionally, what schools are particularly well-known for their programs on this subject?

Communications is not a humanities major.

What category would you group it in, then? I really wasn’t sure.
