Amazon’s new show The Grand Tour is already breaking records after just one episode.

The show was Amazon’s most watched premiere, the company announced Monday, taking the No. 1 spot from the record-breaking debut of its series The Man in the High Castle. Millions of Prime members streamed the first episode of Grand Tour in the U.S., U.K., Germany, Austria, and Japan, the company said, without revealing an exact number of viewers.

Other than a successful debut, Amazon also sold a record number of Prime memberships on Friday. According to the company, Prime membership sign-ups exceeded all previous days, with the exception of its annual Prime Day. The increase was thanks to a one-day price cut of its annual Prime membership fee from $99 to $79—a price that saved new members about 20%.

The show’s success is great news for the e-commerce giant, especially because it reportedly cost the company around $160 million to acquire, according to CNBC. However, Netflix’s chief content officer Ted Sarandos said this number is most likely low—instead suggesting it was “about a quarter of a billion dollars.”

“The guys are back, doing what they do best—the chemistry between Jeremy, Richard, and James is what makes The Grand Tour so entertaining,” said Jeff Bezos, CEO of Amazon amzn , in the press release.

He continued: “Their creativity, along with the amazing production quality and 4K HDR streaming, has Prime members responding in a big way. Kudos and congrats to the whole team.”

Episode two of the 12-week series will be available on Amazon Prime this Friday, the company said.
