Amazon.com has confirmed video streams on its Prime Instant Video service almost tripled year-over-year, thanks in part to the company spending more on new content and original shows.

The company has not revealed the actual number of video streams or how many people accessed Instant Video during this time period however.

Recently, Amazon has been working hard on producing original content like "Alpha House" and "The After," which was developed by "The X-Files" creator Chris Carter.

Instant Video is available at no charge for Amazon Prime members.

Prime members pay an annual fee to receive free shipping for select items.

"We've invested hundreds of millions of dollars in great TV shows and movies for Prime members, and it's working," Bill Carr, vice president of digital video and music for Amazon, said in a statement, according to Reuters.

A number of competitors who offer streaming video, like Netflix and Roku Inc., have also increased their spending on original content.

Netflix shows "Orange Is the New Black," and "House of Cards" have both received Emmy and Golden Globe nominations. Robin Wright won a Golden Globe for her performance on "House of Cards" earlier this year.

Amazon also unveiled a $99 Fire TV last week, a video and game streaming device, which the company hopes will get more people to shop on its website, and watch its programming.
