VOSDAL stands for Viewing On Same Day As Live and refers to programmes which have been watched via VOD services on the same day as the original Linear broadcast. This includes any level of time-shifting, recording or catch-up services. Linear Television technically becomes VOSDAL as soon as it is paused or re-wound on a (e.g.) Sky+ box. This method of viewing is arguably more affected by promotion leading up to the broadcast of the programme and therefore a useful tool for broadcaster’ promotion departments.
