Further emphasizing its streaming prowess, Nielsen's annual data reports highlight "Grey's Anatomy's" consistent high performance. In both 2024 and 2025, the series was the second most-streamed title overall, trailing only the animated preschool hit "Bluey," with over 40 billion minutes streamed annually. In the preceding year, 2023, it secured the fourth position with an impressive 38.6 billion minutes of viewership. This sustained high engagement demonstrates the show's massive and dedicated viewership base.

Currently, "Grey's Anatomy" is available for streaming on multiple platforms. All episodes, including new installments from its 22nd season, are accessible on Hulu the day after their broadcast on ABC. Additionally, Netflix hosts the first 21 seasons of the series, contributing significantly to its aggregated Nielsen viewership figures.
