I commonly use the verb "CC" (carbon copy). I know I could use the word "copy" instead, but I prefer to say "CC" (pronounced see-see). For example, I might say (and have told my co-workers):

I will CC you on that email.

But what's the past tense of the verb CC? Is it "CCed" (which seems strange)? I find that to be strange, so I usually apostrophe it to "CC'd" (which draws more attention to the strangeness).

And no, I don't want to say "copied."

Please provide proof in the form of a similar case with a different strange verb (eg. google => googled).

Analogy with a different verb can be useful for illustration, but isn’t really something the kind of “proof” one should look for — insofar as there’s any gold standard of proof in language, it’s usage data. –  PLL Apr 3 '11 at 3:17

The OED gives the past tense of the verb cc (which it says is also spelled CC) as cc’d or cced. There are two citations for cc’d (1990, 2005) and one of cced (2000).

It also gives the past tense of OK as OK’ed, OK-ed, or OKed, but says nothing more about it.

I suspect an interesting history exists with regards to an apostrophe being used in place of commonly expected letters. Contractions and words such as O' see apt. More recently, many tech terms get 'd -- CC'd being the current example. –  MrHen Apr 3 '11 at 15:43
OED is great. I'm not surprised in retrospect that they have a guideline for this. –  ashes999 Apr 7 '11 at 15:13

CC'd or carbon copied should be fine. I don't find either strange.

For analogy, consider OK'd (also okayed).

I think "courtesy copy" as opposed to "carbon copy" is a more in vogue expansion with email being so prevalent. –  opello Jul 30 '13 at 17:51
