Do a little research on media in an academic discipline (program, major, etc.) and/or a profession, career, or field that appeals to you.
You might consider how media (new media? electronic ones? social media? legacy media?) are used, incorporated, studied—or are changing—the field you choose.
You can read around online (give links!), talk to experts (give quotes!). Use any relevant sources you can find to get a sense of the “media ecology” of the field, and then share it with us.
