Our DVD and Blu-ray sales estimates are based on weekly retail surveys, which we use to build a weekly market share estimate for each title we are tracking. The market share is converted into a weekly sales estimate based on industry reports on the overall size of the market, including reports published in Media Play News.

For example, if our weekly retail survey estimates that a particular title sold 1% of all units that week, and the industry reports sales of 1,500,000 units in total, we will estimate 15,000 units were sold of that title. The consumer spending estimate is based on the average sales price for the title in the retailers we survey.

We refine our estimates from week to week as more data becomes available. In particular, we adjust weekly sales figures for the quarter once the total market estimates are published by the Digital Entertainment Group. Figures will therefore fluctuate each week, and totals for individual titles can go up or down as we update our estimates.

Because sales figures are estimated based on sampling, they will be more accurate for higher-selling titles.

This week's list is highly frustrating for two reasons. Firstly, while there's a pretty big list of first-run releases, many of which had some pre-release buzz, almost none of them matched expectations.

(Even 15 minutes of the Smooth Jazz Nyan Cat wasn't enough to calm my nerves.) Moving on... There were two main contenders for Pick of the Week, Paul on Blu-ray and Stargate: Atlantis: Complete Series Megaset on Blu-ray. In the end I went with the latter, partially because the screener for the former hasn't shown up yet. More...
