As of my last update, Grey's Anatomy was available on several streaming platforms, but availability can vary based on your region and the time you check, due to changing licensing agreements. In the United States, all seasons of Grey's Anatomy were available on Netflix, and it's often the go-to platform to catch up on past seasons of the show. Additionally, new episodes tend to be available on ABC's own platform (with a cable subscription) and potentially on Hulu shortly after they air. However, since streaming rights can change and services may only have certain seasons at any given time, it's always a good idea to check the current status on each platform, or on a service like JustWatch or Reelgood that aggregates streaming availability based on your location. Keep in eye on Disney+ as well, especially since Disney owns ABC, and they might add Grey's Anatomy to their library in regions where they launch their Star channel within Disney+ that focuses on more mature content which includes TV-14 and TV-MA rated shows. Remember to check whether these services are available in your country and what seasons they currently have. If you are looking for ways to watch it for free, remember that this may involve questionable legality and risks to your system's security. Always choose legal streaming options to support the creators and ensure you're watching safely and legally.
