Amazon reported a significant increase in Amazon Prime memberships around the world in 2015, according to Android Central.

Overall, paid Prime memberships jumped by 51 percent over the course of 2015, with the U.S. seeing a 47 percent increase alone. Amazon doesn't reveal exactly how many Prime subscribers there are around the world, but a 51 percent jump is impressive nonetheless.

The growth is clearly driving more customer engagement with Prime's streaming services. Some other interesting Prime tidbits in the report highlights include a doubling of Prime Video streaming customers, along with a tripling of Prime Music streaming hours in the U.S. compared to Q4 2014.

The increase in Prime membership comes as Amazon reports that Q4 net sales totaled $35.7 billion, which is up 22 percent from $29.3 billion in Q4 2014. Meanwhile, full year net sales increased to $107 billion in 2015, compared to $89 billion throughout 2014.
