Amazon Prime Video has introduced a new Watch Party feature for group viewing sessions with up to 100 people. The feature allows Prime members to watch the same content with playback synchronized. Currently, it’s only compatible with Prime Video content and only through the desktop website.
To use the feature, find any Prime Video content through Amazon’s website and click the Watch Party icon near the top of the page. You’ll be asked to enter a name that will be displayed to other viewers of your Watch Party in a chat window. You’ll be given a link to share with friends and family to join your Watch Party. The host/creator of the Watch Party controls media playback that gets synced with everyone watching.
