While 
Apple has a well-earned reputation as the inventor of new markets, it’s also something of a serial killer.
The company’s advances in digital music players made the Walkman an afterthought. The introduction of iTunes sounded a virtual death knell for many record retailers. The iPad cut the legs out from under the once fast-growing netbook PC market. And the iPhone has put Motorola in a fight for its life.
As 
Hollywood continues to expand its options for how and where auds access its content, Apple is amping up the capabilities of the devices on which they consume that content, announcing Wednesday the forthcoming release of a 4G-compatible iPad, a high-def version of its Apple TV device and the expansion of its iCloud storage service to include movies.
Following much speculation regarding what innovations the next-generation iPad would feature, the company revealed that the new tablets will harness the next generation of 4G networks of Verizon, AT&T and other carriers worldwide and feature the Retina display that’s now part of the iPhone.
