As media continues to evolve, audiences are becoming more segmented and selective in their media consumption, choosing from a growing number of specialized sources. However, the potential still exists for media to reach mass audiences. Convergence refers to the combining of multiple media functions into single devices. Audiences now have more control over what media they consume and when due to technologies like DVRs and on-demand services. Multi-platform distribution allows content to be delivered through various methods and devices. User-generated content shared online further engages audiences and reflects the collaborative nature of Web 2.0. The growing use of mobile devices makes media increasingly portable. Social media facilitates online participation and conversation among large networked audiences.
