Which is the correct usage?
From what I just read, "programmed" is the preferred spelling, but in American English there's an alternate spelling of "programed."
Which is the correct usage?
depends on the spelling of program / programme.
The later is the standard British spelling outside of computer usage.
If you use the British spelling of 'to programme', then it's always 'programmed'.
If you use the American spelling 'to program', then both spellings 'programmed' and 'programed' are correct, but you should be consistent.
See especially the usage notes in Wiktionary.

Thanks for the answers. Since the MC is American, I'll stick with programed. I paused as I've seen it both ways in various dead tree works.
SOL advanced search:
programmed - 1000 files (ie SOL stopped counting at 1000 and there are probably considerably more)
programed - 117 files
As an editor, I would always correct 'programed' to 'programmed'.

According to Google's Ngram viewer (word frequency in published works), the two-m variant is by far the most common across the board. Single-m reached maximum usage in 1964 and declined fast, but has started rising again (very slowly) as of around 2009.
Note that when I say more common, in works published in 2019 the two-m version is about 50 times more common than single-m.

I'm American and was in IT. I had never seen "programed" before you brought it up. The preferred spelling for Americans is "programmed" so I'd go with that.

I'm American and I'm still in IT.

I won't go so far as having never seen "programed", but it's so rare vs "programmed" that I would consider it a typo.
As an IT professional in the US, in my experience, programmed is far more common than programed.

I agree, I rarely see programed and when I see it I consider it a typo. If you use the pronunciation rules then programed is wrong.
There's an overwhelmingly preference for programmed.

If you do an ngram search on "programmed, programed" you'll see that "programmed" is the one overwhelmingly used. And it looks like "programed" had its peak in the early 1960s (with "programmed" still way above it) and basically died out late 1980s.
As an American programmer (not "programer"), I would consider "programed" to be an error, though apparently the Mozilla dictionary doesn't agree.
Standard English orthography (yes, there is such a thing) would make the 'a' in "programed" long (it'd be the past tense of the notional verb "programe"). Doubling up the terminal consonant keeps the 'a' short.
