Strength in numbers

Trade and industry magazine MCV has posted a top ten of the biggest-selling single SKUs of all time, and Nintendo's on top.

An SKU is a "stock-keeping unit" — a product with a unique barcode — and is used to separate the same game on multiple formats. MCV's list looks at the biggest-selling SKUs in UK history, with no fewer than seven Nintendo titles in the mix.

Mario Kart Wii tops the list with 3.65m sales, just above the 3.64m sales of Dr. Kawashima's Brain Training. Wii Play, Wii Fit make up third and fourth, ahead of PS2 behemoth Grand Theft Auto: San Andreas. The full chart is available at MCV.

Nintendo titles also top the revenue chart, with Wii Fit raking in £110m, ahead of Mario Kart Wii's £97m. Both figures only include the software's value, ignoring the value of the included accessory. With £66m, Brain Training has made more money than Call of Duty: Black Ops on PS3.

Statisticians and number fans are well served at MCV, with an eyebrow-raising graph of Wii accessory sales too.
