broadcast service

Broadcasting is a broadcast service. Typical transmission technologies for broadcasting are radio and television in their various forms. Broadcast services can be transmitted terrestrially, via satellite or via online media.

Online services exist for many tele- and data communication technologies. These range from telephone and fax to online media such as Internet television and satellite services for radio, television and navigation systems.

In the case of fax machines, it is a feature by which a message is read into a memory and then automatically sent to a specified group of subscribers at a specified time. In other broadcast services, it involves sending voice messages or videos. Social media in particular support the sending of information to specified user groups.
