What does AV mean in this context? The word “AV” does not appear on the linked page. First I thought antivirus but when clicking through I thought maybe audio-video though I doubt it’s that either. Edit: It’s probably meant to mean “audio/visual” as this is what it’s described as. Would be better for the title to say that too.
