What can someone do with a major in history? This answer may not be as specific as, say, someone who majors in nursing, but it does give you a broad field to work with. Most commonly you would see history majors in academia or even teaching high school. But this is not the only option, many lawyers have degrees in history before they go to law school. After a quick Google search for "Careers for history majors" here a few that came up:

Museums and Historical Organizations

Cultural Resources Management and Historic Preservation

Think Tanks

Writers and Editors

Journalists

Documentary Editors

Producers of Multimedia Material

Historians As Information Managers

Archivists

Records Managers

Librarians

Information Managers

History is a field that gives you a very broad selection of careers to pursue, and the more advanced degrees will begin to narrow down to a specific period or theme. This is when you see many history majors being authors and doing further research in their field, or working with universities to get their research funded. Several of the professors that teach at my university have been to the Middle East and Western Europe to do research, completely funded by either the university or grants.

The skills that one learns while working towards a degree in history, or similar social sciences should also not be overlooked. These fields usually require much more research oriented work than many others, as well as developed critical thinking skills to sift through "What if.." and "What led to this..." scenarios. These are skills that can be applied to most any job outside of academia.
