These are some history about the communication software application
E-mail started in 1965 as a way for multiple users of a time-sharing mainframe computer to communicate. Basic text chat functionality has existed on multi-user computer systems and bulletin board systems since the early 1970s. In the 1980s, a terminal emulator was a piece of software necessary to log into mainframes and thus access e-mail. Prior to the rise of the Internet, computer files were exchanged over dialup lines, requiring ways to send binary files over communication systems that were primarily intended for plain text; programs implementing special transfer modes were implemented using various de facto standards, most notably Kermit. In 1985 the first decentralized chat system was created called Bitnet Relay, whereas Minitel probably provided the largest chat system at the same time. In August 1988 the Internet Relay Chat followed. CU-SeeMe was the first chat system to be equipped with a video camera. Instant messaging featuring a buddy list and the notion of online presence was introduced by ICQ in 1996. In the days of the Internet boom, web chats were very popular, too. Voice over IP is only taking off now
