Apple Pulls out of NAB 2008
"Apple is participating in fewer trade shows this year," said Anuj Nayar, senior manager of PR at Apple. "Often there are better ways to reach our customers.

In 2007, Apple even held a special event at NAB, announcing a number of updates to their professional video applications.
