Is it a font or a typeface?

The Next Web reports: [edited]

'Font' and 'typeface' are not interchangeable.

'Typeface' should be used when referring to the design, while 'font' should be used when referring to the file, copy or file-type. For example, there is only one Times New Roman typeface designed by Victor Lardent, but nearly everyone with a computer has a copy of that font. A font is what you actually use.

When you talk about how much you like a tune, you don’t say: 'That’s a great MP3'. You say: 'That’s a great song'. The MP3 is the delivery mechanism, not the creative work; just as in type a font is the delivery mechanism and a typeface is the creative work.

Font is what you use, and typeface is what you see.

This subject is not without controversy. Some believe that 'font' or 'font family' refers to a collection of typefaces as well as the file, while others argue that 'type family' is the proper term.
