The NAB2005 Show in Review
The annual trek to Las Vegas is behind us, and overall impressions of the convention are positive. As always, the foot traffic on the convention floor was heavier on Monday and Tuesday, but Thursday still saw a reasonable number of people still making their rounds. Conversations with attendees and exhibitors were marked with mostly positive remarks about the success of the show. It appears that broadcasting is on an upswing.
The most frequently asked question on the convention floor sought information on new products being displayed. If you weren't able to make the rounds to every booth, don't worry. We covered it for you. The March and April issues of Radio magazine had lots of information about products being unveiled, as did the NAB Insider e-mail newsletter, but they only scratched the surface. On the following pages you'll find details about some of the products that were kept secret until the convention doors opened. You'll also find the top picks of our Pick Hits judges with the 15 top new products at the convention. The Radio magazine Pick Hits are the oldest technology awards from the convention, and our panel of judges has excelled in its task to find the best of the best. Because the Pick Hits are limited to 15 products, there are many introductions that do not receive the honor. The Pick Hits are included on the following pages. You can see the list of the judges and the official rules as well.
Because of the scope of convention, it's impossible to include every new product introduction even in the pre- and post-show issues. Look for more great products in the New Products section of upcoming issues, as well as the annual Product Source accompanying the September issue.
