Do you say program or programme? Which one is original english? Which one should we use?
Acording to Wiktionary, programme is the British spelling and you can therefore assume that program is the American spelling.
Also, according to Google Ngram, programme was originally the most common spelling but was then overtaken by program in around 1913.
As for which one you "should" use, well, do as you wish. I personally like to use archaic words that aren't spoken often anymore so I'd say go with programme if you're asking me.
