If you like watching HBO shows including "Six Feet Under," "The Wire" and "The Sopranos" on Amazon Prime, you might want to binge watch before the content is taken down.

HBO doesn't plan on renewing its deal with Amazon Prime, and will pull the channel’s library content from Amazon Prime Video after the pact ends in mid-2018, HBO Chairman and CEO Richard Plepler told investors Wednesday during Time Warner’s first-quarter earnings call, Variety reported.

“I don’t think you’ll see us extend or expand our library programming on Amazon beyond the end of next year,” Plepler said.

The move shows HBO is focused on growing the number of subscribers on its HBO Now standalone service. HBO had teamed up with Amazon Prime and other digital content providers to market HBO Now.

Plepler added HBO will take advantage of the “enormous momentum” of signups through Amazon, as well as sales through AT&T’s DirecTV Now. AT&T and Time Warner, HBO’s parent, are in the middle of a $85.4 billion merger, which is expected to close at the end of the fiscal year.

Plepler's comments suggest HBO sales are strong enough that the licensing deal for a number of older series, including "The Sopranos" and "The Wire," is no longer needed. HBO Now includes a large library of nearly all of the channel’s original series of the past 30 years. Since Amazon offered the same shows on Prime, it conflicted with HBO Now.

HBO and Amazon Prime sealed a four-year deal in the spring 2014 and was estimated to be worth $250 million to $300 million. The HBO service launched on Amazon Prime in 2015. The deal specified newer shows would become available on Amazon three years after a series finished running on HBO. This means Prime customers probably won’t be able to see newer series such as "Game of Thrones," "Girls" or "Westworld."

HBO’s move will end up pushing viewers to purchase HBO Now or another service to watch the channel's older shows.

HBO introduced HBO Now just months shortly after making a deal with Amazon Prime. HBO Now is currrently available for $14.99 as a standalone service. New customers can get a one-month trial when signing up. You can watch HBO Now on any supported device, including iPads, smartphones and TVs, as well as online at Hbonow.com.

There is also HBO Go if you have a cable provider. The service is included when you pay your HBO subscription through a TV provider. Both HBO Now and HBO Go support simultaneous streaming, which means various people in a household can sign-in and watch HBO shows, movies and other content on different devices.

Meanwhile, you'll have about a year to catch up on the classic HBO shows before they're taken off Amazon Prime.
