Amazon updates Prime efforts

Amazon saw Prime membership improve 53% year over year, including 50% growth in the U.S. During the quarter, the company announced one- and two-hour deliveries in Manhattan and Prime Photos for unlimited photo storage.

“Prime is a one-of-a-kind, all-you-can-eat, physical-digital hybrid — in 2014 alone we paid billions of dollars for Prime shipping and invested $1.3 billion in Prime Instant Video,” said Amazon founder and CEO Jeff Bezos in a statement. “We’ll continue to work hard for our Prime members.”

Amazon has also made headway with original content, taking on Netflix with its Prime-exclusive series Transparent, which won two Golden Globes.
