A broadcaster device generates a live stream including video-based commentary regarding a live event combined with an audio and/or video feed of the live event itself. A viewer device receives a copy of the integrated live event and commentator stream and synchronized event information (e.g., real-time scores), and displays the integrated stream and the event information (e.g., as a “scorebug”). Viewers of a given live event may seamlessly select amongst different broadcasters for the same live event to access different integrated live event and commentator streams respectively synchronized with the event information. A social media platform is provided in tandem with live streaming of digital content relating to live events to allow a given broadcaster and their associated viewers to communicate with one another, comment on the event and/or the broadcaster's live stream, and send digital gifts.
