Hum opening of television program (3)

I believe the answer is:

bot

'program' is the definition.
(a computer program)

'hum opening of television' is the wordplay.
'hum' becomes 'BO' (body odour - hum can mean a smell).
'opening of' indicates taking the first letters.
The initial letter of 'television' is 't'.
'bo'+'t'='BOT'

(Another definition for bot that I've seen is " machine".)

I've seen this clue in The Guardian.
