In a previous article, I ranted about the use of apostrophes for plurals. I hate them!

Someone asked me if it was correct to make acronyms plural with an apostrophe. The answer is simple. No. It doesn’t make any difference. You shouldn’t use an apostrophe to make an acronym plural. For example:

  1. There are four ATMs in the mall.
  2. NGOs must conform to the rules established by their boards.
  3. All the VIPs were given a glass of champagne.
  4. I gave away all my CDs.

If you are talking about possession, though, it’s fine to use an apostrophe. (He scribbled on all over the CD’s label.)

The only exception to this rule, according to The Chicago Manual of Style, is “when an abbreviation contains internal periods or both capital and lowercase letters.”
