Teleparty, formerly known as Netflix Party, is a browser extension that allows users to synchronize their streaming video playback across multiple devices. It enables friends and family to watch movies and TV shows together remotely, even physically apart. With Teleparty, users can chat in real time while watching content, providing an interactive and social viewing experience. The extension supports various streaming platforms, including Netflix, Disney+, Hulu, and HBO. Teleparty has become particularly popular when people cannot gather in person, offering a virtual solution for shared entertainment experiences.
