Apple, Hewlett-Packard, Compaq, 3Com, Nortel and Xerox have banded together to form what they are calling “The Anti-Gray Market Alliance,” Bloomberg reports. The Alliance — based in Arlington, Virginia — will strive to educate consumers about the dangers of purchasing their products from unauthorized resellers and map out guidelines companies may use to stop the practice (a market estimated at US$20 billion in 2000). Reuters is also carrying the story.
