We can also send SMS (Short Message Service) instantly through our mobile phones. Fax machines are used to sent written messages instantly.
Computers and the Internet have made communication even more faster and efficient. We can use email services such as Gmail and Yahoo mail to send e-mails (electronic mails) instantly through internet.
Mass communication is a process in which a person, a group of people, or an organization sends a message through a channel of communication to a large number of people at the same time.
