B-VOD is Broadcast VOD is the method by which traditional broadcasters can offer another way of viewers accessing their content. This only refers to content previously or simultaneously released on another channel (often but not exclusive to Linear TV). Interestingly, due to the commercial nature of many of the traditional broadcasters, BBC iPlayer is the only solely B-VOD service, as other B-VOD services (e.g. Sky Go or ITV Player) also fall in to A-VOD or S-VOD categories due to the nature (e.g. commercial) of their services.
