David, a long term trend in US research universities is 'area studies' replacing the centrality of departments, and also taking on the function once identified with 'principal subjects'. This applies both to students and to faculty researchers. Film Studies may be part of an English Dept, or a of a Theater/Cinema Arts Dept, or be an interdisciplinary program whose teaching faculty are drawn from various conventional departments.
A Department of History may include specialists/concentrations in Medieval studies, East Asian studies, Caribbean studies, etc. The department serves as a tenure home for faculty with appropriate terminal degrees; offers an undergraduate major (BA) plus general lower division courses required by the university for all undergrads; offers graduate degrees (MA, PhD). The History faculty may have joint appointments in other programs (Environmental Studies, Ethnic Studies, Women's Studies, Latin American Studies come to mind at the University of Oregon, where I work) that offer bachelor and/or masters degrees but not the doctorate.
Many departments now widely accepted (Anthropology, Economics, e.g.) did not exist in the 19th c; go back several hundred years in Europe and you have the Quadrivium, the four principal permissible subjects. After our lifetime, higher education will evolve other standard disciplinary standards for naming subjects and credentials. 'Area studies' points toward the next probable stage, but change will be slow, largely because educators rely on widely accepted, transferable standards in credentialing.

Roger: for my own fun, and to entertain postal workers, I often spell my return address (city, state) as Evgeny Onegin. Owing to my chickenscratch handwriting (and universal acceptance of zip codes), hardly anyone notices. But perhaps it will entertain Frances. Funnier though is that Eugene (Oregon) is the first not the last name of its 'founding' ferryman/postmaster/mayor, Eugene Skinner. The runner-up name for our tie dyed Birkenstocked community was Charnelton, but luckily some wag with a degree in history or classics or linguistics pointed out that only a city of the dead would call itself Charnel Town. (Yet Charnel was also a first name, of the 'second citizen' surnamed Mulligan. This place has always been a little weird.)
