Systems, devices, and methods for delivering and managing media whereby a first media element contains multiple media components and a combination of user activity and time are necessary to unlock a subset of the multiple media components. In one embodiment, the user activities include serving as a peer leader, purchasing a key that unlocks at least one of the multiple media components, and other activities having value to the system. The system may also update the media components individually, or in parallel. In addition, the requirements for unlocking one or more of the media components may vary dynamically, or the media components may vary based on: known individual characteristics of a user in a group of users, group characteristics of a subset of users within a group of users or other criteria.
