In his annual letter to shareholders, Jeff Bezos, Amazon founder and chief executive officer, announced that the company's Prime service now reaches 100 million members worldwide. The company has also shipped more than five billion items and convinced customers to buy "tens of millions" of Echo devices, he wrote.
That success, in part, could explain why Bezos' net worth was just shy of $130 billion Thursday.
And if you invested in Amazon early on, you wouldn't be doing too badly either. Your initial outlay of $1,000 in 2008 would be worth more than $19,300 Thursday, according to CNBC calculations, or over 19 times as much, including price appreciation and dividend gains reinvested.
