You can watch The Sopranos on several streaming platforms depending on your location:

• In the US, The Sopranos is available to stream on Max (formerly HBO Max), which offers all six seasons

• It is also available on Hulu for streaming

• You can buy or rent episodes on Amazon Video, Apple TV, Sky Store, and Microsoft Store

• In the UK, all episodes are available on Sky Atlantic, Sky Go, and NOW TV

• Additionally, the first two episodes are sometimes available on YouTube as part of HBO's promotions, but the full series is primarily on paid platforms

For the most comprehensive access, subscribing to Max is recommended as it is the official HBO streaming service carrying the entire series. If you are in the UK, NOW TV or Sky platforms are the main options
