‘Digital convergence’ refers to the profound changes in the structure of media caused by the emergence of digital technologies as the dominant method for representing, storing, and communicating information. In the past, information and communication technologies were segmented into discrete economic and technical systems with minimal capabilities for interoperability.
Digital convergence can be defined in terms of the following three developments
The coming together, into a single application or service, of information content from sound broadcasting, telephony, television, motion pictures, photography, printed text, and money.
A growing amount of overlap in the functions that can be performed by different physical telecommunication networks.
A growth in the interactivity, interoperability, and connectedness of different networks and information appliances in the home and the office.
