The word "telecommunications" refers to those organizations (both commercial and noncommercial) involved in the production and distribution of information and entertainment via electronic communications media.
It is derived from the Greek word, "tele" which means
far away or transmission over a long distance. 

The prefix "tele" can be found in such words as: telephone, television, and telepresence to name
onlya few. 
In my various courses,I address two very differenttypes of telecommunications players, including electronic media organizations and common carriers. 
The 21st century promises a very different set of industry  players than 
was the case in past years.
