"Each touts distinct benefits: 1-800-411-SAVE offers callers advertiser discounts; 1-800-FREE-411 was first to launch and trumpets its memorable brand; and 1-800-411-METRO automatically connects calls to businesses. 'Even if the three of us were to split a small piece of the (411) market, that's still a giant number,' says Mike Loftus, CEO of InFreeDA, which operates 1-800-411-METRO."
