Amazon recommends clean underwear

Amazon.com wants you to be sure to have clean underwear, no matter what else you’re buying.
On Wednesday Amazon.com made the shocking admission that it doctors some of its product recommendations, which are supposedly compiled by objective software that compares each customer’s purchasing history with the histories of others who’ve made similar purchases.
For instance, the page for the DVD “Titanic” states, “Customers who bought this DVD also bought ‘Forrest Gump,’ ‘Saving Private Ryan,’ ‘Gladiator,’ and ‘Independence Day.’ ”
But Amazon.com said some of the recommendations for additional products are made up.

When a similar sort of thing happened with search engine, Google entered the fray. I wonder whether Google will come up with a “product search” too.
