Aspects relate to pushing of content for use on mobile devices, and subsequent retrieval of such pushed content for concurrent presentation with voice and/or video data transmitted to the mobile device. The pushed content can be indexed and otherwise synchronized with the voice and/or video (or otherwise controlled by a presenter) through a group messaging channel. A calendar entry can include a link to the pushed content, such that activation of the calendar entry can also cause a content presentation application to load and begin presenting a portion of the pushed content. A link to local storage of such pushed content can be provided in such calendar entry. The content presentation application can monitor device events or interrupts in order to detect an event indication generated from the calendar application.
