Publishing Key Frames Of A Video Content Item Being Viewed By A First User To One Or More Second Viewers

A device receives key frame information for each of a plurality of key frames of a video content item and sends the key frame information from the device to a recipient while a corresponding segment of the video content item is being rendered by the device. The key frame information may include key frames of the video content item, references to the key frames of the video content item stored by one or more remote sources, or information identifying the key frames of the video content item to enable extraction of the key frames by a recipient device. Each key frame is representative of a segment of the video content item. The key frame information for the video content item is then sent to second users while the first user views the corresponding segment of the video content item. Advertisements may be sent with, or replace, the key frame information.
