“Twenty years ago, I was driving the packages to the post office myself and hoping we might one day afford a forklift. This year, we pass $100 billion in annual sales and serve 300 million customers,” Amazon Founder and CEO Jeff Bezos said in a statement. “And still, measured by the dynamism we see everywhere in the marketplace and by the ever-expanding opportunities we see to invent on behalf of customers, it feels every bit like Day 1.”

Amazon Web Services posted net sales of $2.4 billion, which was a bit ahead of the consensus at $2.3 billion. The company wasn’t breaking out revenue for Amazon Web Services in the year-ago quarter, although last year analysts were estimating it at about $1.5 billion, according to MarketWatch.
