Any non-live viewing to programmes that takes place within 164 hours (approx7 days) of the original broadcast is reported as time-shifted viewing. This includes playback through PVRs, DVD-recorders or VCRs as well as via catch-up services available through the TV.
Time-shifted viewing through TV sets has continued to increase in recent years (see Chart 1) and reached a new high in May 2011. During that month time-shift accounted for 9.1% of reported viewing, up from 7.1% in May 2010.
A substantial proportion of all 7-day time-shifted viewing actually takes place on the same day as broadcast – 46% in May 2011. This is reported as VOSDAL (Viewing On Same Day As Live) and normally included as standard in reported overnight figures.
Charts 2 and 3 show how the proportion of viewing that is time-shifted varies by demographic group. Broadly speaking time-shifted viewing is a higher proportion of viewing for young adults and ABC1s than for other groups. Time-shift viewing also varies widely by programme genre. Chart 4 demonstrates this, based on data for May 2011. Not surprisingly news programmes were only rarely time-shifted but for drama series time-shifted viewing accounted for 20% of the total. Among individuals with a Sky+ PVR this proportion rose to 36%.
