Amazon racks up "tens of millions" of new Prime subscribers over holiday

Amazon announced this morning it had a record-breaking holiday season with the company adding "tens of millions" of Amazon Prime subscribers while also selling millions of Amazon devices worldwide.

Why it matters: Like any retailer, one of Amazon's goals is to sell customers their own products and devices. But larger than that, Amazon's bigger goal is to convince these shoppers to subscribe to their other services, such as Prime Video. Numbers show they accomplished that in a major way this holiday season.
