"on the BNC" vs "in the BNC"

Should we say “on the BNC” or “in the BNC”?
(“in the BNC” seems to me as something is cited from the corpus while “on the BNC” seems to focus in the website of BNC)

Hi,

‘In’ is preferable since it’s like a document/book of information. It’s not like ‘on the TV’ or ‘on the radio’.
