The present technology is generally directed to multi-user screen sharing. In some embodiments, a method for media content screen sharing includes receiving a first media content item selection from a first user and receiving a second media content item selection from a second user. The method can further include generating a multi-content video signal, wherein the multi-content video signal includes the selected first media content item and the selected second media content item. The multi-content video signal can be displayed to both the first user and the second user. The method can include causing a first electronic device of the first user to display a first portion of the multi-content video signal that corresponds to the selected first media content item, and causing a second electronic device of the second user to display a second portion of the multi-content video signal that corresponds to the selected second media content item.
