The origin of email – how it all began

Email, better known as Email, has changed the face of communication over the decades. Email can be defined as a method for composing, sending, storing and receiving messages through electronic communications systems. The word "email" is used both as a noun and a verb, and refers to all Internet email systems based on SMTP, X.400 systems and intranet systems.

How did it all begin?

Before the Internet, there was an email: it was probably the most important tool in the development of the Internet in the late 80's. The Massachusetts Institute of Technology first exposed CTSS (Compatible Time Sharing System) in 1961. CTSS allowed many concurrent users to log on to IBM 7094 from remote dial-up machines and store network files on a floppy disk. This incredible development has encouraged users to share information in different ways. The birth of email was in 1965, when more computer users who shared a time period began communicating remotely and electronically.

Although the complete history and exact dates are rather murky in detail, the first systems to have basic email content were Q32 and System Development Corporation and the Massachusetts Institute of Technology. By 1966, email had expanded rapidly and had become an online mail, allowing users to forward the email between different computers.

ARPANET is undoubtedly a good contributor to email development. Historical reports say there have been experiments on intersystem email transmissions just after it was created in 1969. Ray Tomlinson, a developer who developed a time-sharing system called TENEX, was the first person to discover that different hosts could be different using the @ character to separate the user name and their machine. Up until 1971, when the actual email was discovered, machines could only send messages to users within their own system.

Email has grown in popularity through ARPANET and over time, email has become a basic Internet communication technology.

Ray Tomlinson – Detect Online Email

The first person to discover the ability to send an inbox between different computers over the network, Ray Tomlinson is the person to thank for the groundbreaking outcome of "email." Although there have been many cases where messages were passed between different users within the same computer and made quite an impression among users, the real email as we know it today started with the first online email.

Ray Tomlinson was involved in a group that developed a time-sharing system called TENEX running on PDP-10 digital computers, working on network control protocols for both TENEX and CPYNET (an experimental file transfer program). While making improvements to SNDMSG, a local mail program available to users at the time, Ray Tomlinson realized that he could easily integrate code from CPYNET to SNDMSG and transmit messages via a network connection to remote mailboxes. as well as attach messages to local mailbox files.

Including SNDMSG and CPYNET features, it was able to develop a networking program and test it on two machines literally side by side. He used the @ sign to distinguish different machines in a very simple way, such as "from: me @ thismachine to: you @ thatmachine". After testing the program several times, sending a message back and forth between two computers, he sent a general message to his group explaining how to send the message online. And so the first online e-mail was created.
