So, even collective nouns can be plural?
Well, actually, "media" isn't a collective noun—or, more accurately, it has
historically been considered incorrect to treat "media" as singular.
"Media" is actually just the plural form of "medium" (= a particular format in which audiovisual content is transmitted; for instance, FM radio is
a medium).
The plural form isn't "mediums" because it's still faithful to the original Latin—much like "maxima" and "minima" (the plurals of, respectively, "maximum" and "minimum"), which you've certainly seen if you've taken introductory calculus.
This issue is currently in flux. More and more users are using "media" as a singular noun; eventually, once that critical mass of 'wrong' users is an overwhelming majority, that will become an 'alternative correct form'.
While we're all here, precisely the same situation obtains at this moment for "data".
"Data", like "media", is a Latin plural. The singular is "datum", which is the proper formal word for what many people call a "data point".
Careful formal writers still won't use singular "data", but—just as is the case for "media"—more and more English users are gradually, through crowd action, legitimizing singular "data".
The other thing you need to know is that there are departures from the 'looks singular'/'looks plural' rule in BOTH directions. You could potentially see plural-looking subjects that are actually singular, or singular-looking subjects that are actually plural (or even both!)—as long as there's grammatical proof
somewhere in the sentence.
As an example going the other way, check out
this official problem, which features a plural-looking subject that turns out to be singular.
In that problem, please make sure you can spot the grammatical proof that this subject departs from the usual rule-of-thumb.
