My Internship was for a private Environmental Consulting firm as a GIS Technician. The job was not posted as an internship per se, but as a part time entry-level temporary position. When I interviewed with them, I asked the GIS Manager if we could modify the position to fit the internship requirements, so I could meet my degree requirements (I was working on an Associates in GIS at night at a community college).
I got the position as I already had several years working in the field as an Environmental Scientist (non-GIS), so was already up to speed on how they did business. They had a need for someone who could do GIS, but would also be available occasionally to pitch in on non-GIS projects.
For anyone who is looking for an internship, keep in mind if you have previous experience in a field that marketing it can be a way of getting your foot in the door.
