The digital-streaming market is booming, and that means more wonderful content for all of us to binge-watch on a daily basis. One of fastest growing services offered online is from Amazon, and over the past 18 months, the company’s digital store ‘Amazon Instant Video’ “jumped 53% among websites used to watch movies and TV shows,” this according to the latest report from RBC Capital Markets.

This was the most dramatic increase of any online video service. So we wanted to know what everyone was streaming, and the team behind Amazon Instant Video shared the company’s list of the Top TV Passes Ever. The list below reveals the most popular series over the past year and six-months.

Not a total surprise (though it did have some serious competition) The Walking Dead Season 4 was the number-one hit on the list. New fans and old are catching up on the series just as Season 5 is set to premiere on October 12 on AMC. Season 5 episodes will be available for instant streaming on Amazon Instant Video on October 13, the day after the original network air date.

The complete list of Amazon’s Top TV Passes Ever includes:

  1. The Walking Dead, Season 4 & in HD
  2. Breaking Bad The Final Season
  3. Downton Abbey Season 4 & in HD
  4. Mad Men, The Final Season
  5. Sons of Anarchy Season 6
