Abstract

Described herein are systems and methods for presenting content to a plurality of users at a plurality of computers. Presenting content may comprise presenting media content (e.g., playing media content) such as audio or video content—including music; audio books; image slideshows; movies, television programs, video clips, and other video content; and any other suitable audio and/or visual content—at the plurality of computers to create a shared media experience (e.g., a shared listening/viewing experience) among the plurality of users. In some embodiments, one or more techniques may be applied to ensure that presentation of the content is performed substantially simultaneously (also referred to as synchronously) at each of the computers to ensure that each of the users is experiencing the same content at the same time.

(C1) bounding a size of the group of users to be a sufficiently small group not to qualify as a public performance; and

(C2) streaming media data from a computer associated with one user to computers associated with each of the other users in the group of users in a format that complicates a capture process.

19. The method of claim 18, wherein the size of the group is bounded in act (A1) to be less than 100 users.
