Nielsen's streaming ratings reflect only U.S. audiences and do not account for viewing on computers or mobile devices. The data underscores the show's significant impact on the streaming landscape, as it continues to attract a large audience.

While “Grey’s Anatomy” has enjoyed remarkable success, some critics argue that the series has become formulaic over its long run. They suggest that the show's ability to maintain high viewership may not necessarily reflect its quality but rather the loyalty of its established fan base.
