يک مقايسه خوب بين بيزنسهای گوگل، آمازون، eBay:

"It takes 11,600 eBay employees to make $5.2B in sales while 5,700 Googlinians rack up $8.2B in sales. Amazon.com Inc. (AMZN) moves $9B in actual (not virtual) product with just 12,000 employees. That means that for each dollar in revenue an eBay employee oversees as clicks move through their computers, an Amazon employee generates $1.60, while they order the item, stock the item, package the item, ship and bill for the item..."
