“Tom Clancy’s Jack Ryan,” the Amazon original starring John Krasinski which launched in August, attracted nearly 40 percent of Prime Video users in the first month after its premiere, according to new data from 7Park Data shared exclusively with TheWrap.

According to 7Park, 37 percent of Amazon Video viewers watched the series last month, which is well above the average audience share of 9 percent.

A rep for Amazon Prime did not immediately respond to a request for comment.

Other Amazon Originals following “Tom Clancy’s Jack Ryan” were “Man in the High Castle” (23 percent), “Hand of God” (22 percent). “Sneaky Pete” (19 percent) and “The Grand Tour” (18 percent), according to 7Park.

Part of the reason for the high percentage of viewers tuning in to “Jack Ryan” for its first month had to do with the series premiere, which took place August 31. Because it’s common for users to binge-watch a season as soon as its released, most new series experience a spike in viewership within the first week after their premiere.

The same trend can be seen with seasons 1 and 2 of “The Grand Tour” when taking a look at the 7Park graph below.

This is the first time 7Park has tracked Amazon data. While the company has been tracking viewership metrics of both Hulu and Netflix, today it announced the addition of Amazon Prime Video viewership data to its Streaming Intelligence data product.

The new offering includes valuable insights into streaming behavior in more than 50 countries. 7Park Data’s Streaming Intelligence aims to help its clients better understand audience behavior in order to make better decisions about development, licensing, and marketing.
