Amazon has essentially created a new shopping bonanza in the same vein as Black Friday and Cyber Monday, through its Prime Day event that takes place each July. On its fourth annual Prime Day, which concluded yesterday, Amazon again reported records sales, and the PC category contributed to it.

Specifically, of the 100 million items Amazon sold during the 36-hour event, the "PC and accessories" category accounted for 5 million of them. It's not clear how that breaks down in terms of revenue. As it relates to item sales, however, a 5 percent chunk is not insignificant considering the many different categories on Amazon.
