Last week Amazon posted its results for the 2016 holiday season, the company’s best ever for devices including the Echo Dot, Fire TV stick, Fire tablet and Amazon Echo. In addition, customers bought more than nine times the number of Amazon Echo devices than last holiday season.

“Echo and Echo Dot were the best-selling products across Amazon this year, and we’re thrilled that millions of new customers will be introduced to Alexa as a result. Despite our best efforts and ramped-up production, we still had trouble keeping them in stock. From turning on Christmas lights and playing holiday music to shopping for gifts and asking for help with cookie recipes, Alexa continues to get smarter every day,” said Jeff Wilke, CEO Worldwide Consumer, Amazon.

Prime members also contributed to Amazon’s holiday success in 2016. Here are some key statistics shared by Amazon.

• Prime members bought more than one billion items
• More people tried Prime this holiday season than any previous year
• The fast Prime Now delivery was on Christmas Eve. It took 13 minutes.
• December 23, 2016 was the biggest day ever for Prime Now deliveries with members ordering three times more items than last year. In addition to Echo devices and Fire TV sticks, Oreo cookies were among the most popular purchases on December 23.
• The last order of the holiday season was delivered on Christmas Eve at 11:59 PM to a Prime customer in Irvine, California.
• Prime members in Dallas ordered more items using Prime Now than in any other city where Amazon offers Prime Now.
• The most streamed Amazon Original Series over the holidays was Goliath.
• Customers listening to holiday music on Amazon Music this year tripled compared to 2015.
• The #1 magazine downloaded in Prime Reading by Kindle customers was People.

Other Amazon highlights for the holiday season include:

• More than 72 percent of Amazon customers shopped using a mobile device
• On Cyber Monday, Amazon customers bought about 46 electronics per second on a mobile device.
• On Cyber Monday, Amazon customers bought about 36 toys per second using a mobile device.
• December 19 was the top worldwide shipping day.
• Four Amazon fulfillment centers (San Marcos, Texas; Kent, Washington; and two centers in Poland) shipped more than 1 million items in a single day.

And the list goes on. Needless to say, Jeff Bezos probably didn’t put coal in anyone’s stocking this Christmas.

Insider Take:

Amazon’s success this holiday season comes as no surprise. Simply put, Amazon makes our lives easier. We no longer have to trek to the mall for holiday gifts, fighting traffic, juggling packages and overspending. We don’t even have to go to the grocery store for milk and toilet paper for that matter. Amazon brings everything we need right to our homes, in a matter of days, or in some cases, minutes or hours. Effortless shopping at reasonable prices.

What’s even better is that Amazon does this for Prime members for one low annual fee of $99. For that fee, we get free two-day shipping, free cloud storage, Amazon Music, access to the Kindle lending library, Amazon Prime Video and much, much more. And with every new product or service added to the Prime membership, we become even more dependent on Amazon for all of our shopping needs. On top of that, Amazon has good customer service and it is easy to use. We can’t see any reason to ever leave. Jeff Bezos is counting on that.
