Programmes of less than 5 minutes duration are excluded from these reports.
The programme audience is the average audience of all the minutes covered by the programme transmission (excluding commercial breaks and promotions).
Where * is shown, the figures are small but not zero.
Weekly programme information on this website is initially posted 8 days after the end of the week. It may subsequently be updated 6 weeks later to include any amendments made by broadcasters to the transmission logs originally provided, and to allow for inclusion of programme data where transmission logs were not provided in time for the initial data release.
When a programme is split into two separate parts on the same day (e.g. by a news bulletin), the audience reported is an average of the network audiences to the two parts weighted by their respective durations.
Up to December 2001 when a programme or episode of a serial was repeated within the same week, audiences to each showing were aggregated within these Top 30 listings. From January 2002 this rule is no longer applies, Top 30 listings up to December 2001 should not be compared with later data.

Where hour and minutes are shown, * indicates that the recorded figure is between zero and half a minute.
