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.

Featured Blu-ray review - Rocky - The Heavyweight Collection

February 8th, 2014

Rocky: The Undisputed Collection came out nearly five years ago and I loved it. Now a new box set is coming out. However, is it any different than before? Or is it a simple cash grab? More...

Contest: Between a Rocky and a Hard Place

February 6th, 2014

Next weekend is Valentine's Day / Presidents Day long weekend and there are four wide releases hoping to take advantage. Of those four, only two have a shot at first place, RoboCop and About Last Night. RoboCop is opening on Wednesday, so that leaves About Last Night as the clear choice for the target film for this week's box office prediction contest. In order to win, one must simply predict the opening weekend box office number for About Last Night. Whoever comes the closest to predicting the film's opening 3-day weekend box office (Friday to Sunday), regardless if they go over or not, will win a copy of Rocky: Heavyweight Collection on The Ultimate Guide to the Presidents on DVD. Entries must be received by 10 a.m., Pacific Time on Friday to be eligible, so don't delay! More...

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.
