Usage
Q. On page 221 (15th ed.) Chicago says “media” is the plural of “medium” in re mass communications. Please advise if these sample adjectival constructions are wrong: public media archives, public media community, the new media landscape, public media practices, media companies, media platforms. Often a substitute noun would be singular: senior community, university practices, computer platforms.
A. Yes, but such constructions can also be plural: seniors community, books archive, problems database, toys catalog. And given that “media” is often construed as a singular noun (see Webster’s 11th Collegiate), your constructions can be considered correct.
