 Re: on Facebook?
"on" is used for the net in the same way as for the TV or radio. The net is not seen so much as a printed medium which you can physically open and look "inside" - like a book or a newspaper - but as a broadcasting medium. The name "Facebook" is irrelevant. Particular sites are seen as being parallel to TV or radio channels.
I saw the news on the television / on the "Today" programme / on BBC1
I heard the news on the radio / on the "Today" programme / on Radio 4
I saw it on the net /on "Youtube"
I heard about it on the net /on "Facebook". |
