Spiderman 3 Blu Ray sells well but not as much as Transformers

"Spider-man 3" becomes the best selling Blu-ray title with 130,000 copies sold in the first six days. "Transformers" did 190,000 units on HD DVD in the same timeframe. Some have speculated that the "Transformers" numbers are exaggerated, but proof has not been presented and Paramount says that they have double checked the numbers.

On DVD Sony was more reluctant to reveal specific numbers, but said that the standard DVD version sold 4 - 5 million copies. "Transformers" did 8.3 million on DVD.
