"While we're still waiting for official Nielsen ratings, our measurement shows that the audience numbers exceeded all of our expectations for viewership," Prime Video's top sports exec Jay Marine said today in a note to staff on the "resounding success" of the streamer's official Thursday Night Football kickoff on September 15.

"Our first exclusive TNF broadcast delivered the most watched night of primetime in the U.S. in the history of Prime Video," the VP Prime Video, Global Head of Sports, also told colleagues in the memo (read it below). "This is a massive achievement. During our TNF broadcast, we also saw the biggest three hours for U.S. Prime sign ups ever in the history of Amazon – including Prime Day, Cyber Monday, and Black Friday."
