WSJ article about companies that are challenging Google.
Internet companies, locked in a fierce battle to get more people to use their search engines, are dangling rewards and cash prizes to attract customers to their sites.
The incentives vary from shot-in-the-dark sweepstakes for luxury-hotel stays and pricey plasma TVs to loyalty programs that offer guaranteed rewards and payouts to those who qualify, similar to those found in the airline and credit-card industries. While the odds of winning big may be slim, the hope is that some regular incentives may persuade some consumers to stop using Google as a starting point for every Internet search.
