Why do we use "cc" in an email?

In the ever-expanding email lexicon, few abbreviations are as ubiquitous as "cc." How has this 19th-century term come to be so important in 21st-century tech?

T he evolution of technology is unrelentingly swift. Generations have witnessed state-of-the-art inventions become obsolete in the blink of an eye. The fax machine, the pager, and the landline, all once revolutionary, have earned their place in the annals of history. Yet email — born in 1971 when engineer Ray Tomlinson sent the very first "ping" — has remarkably endured. This persistent form of communication continues to redefine itself for the digital age, but one enigmatic email feature hasn't changed for 50 years: the "cc."

The "cc" field is a familiar sight perched within the recipient line of an email. The purpose is to send a copy of the message to an additional recipient who might need the information, but isn't integral to the action of the message. Its modern definition traces back to its original usage in the late 19th century, when a duplicate was called a "carbon copy."

Around the 1870s, long before photocopiers, documents were painstakingly duplicated by hand using carbon paper between two sheets of plain paper. Something written or typed on the top page would be transferred to the bottom piece of paper through the pressure on the carbon (essentially ink). The exact replica was called a "carbon copy." By the 1920s, the term "carbon copy" had shifted to figuratively describe something that was a near-identical replica, such as "Mark was a carbon copy of his father." This usage made its way into corporate America in the 1930s, when it was used in business as shorthand to ensure that multiple parties received the same information.

When email emerged in the 1970s, "cc" was quickly adapted, as the jargon was already familiar in professional circles. The concept of the "bcc" (blind carbon copy) soon followed, allowing a sender to conceal recipients entered in the "bcc" field. In the 1980s, the use of "cc" became so prevalent that it evolved into a verb, as in, "I cc'd Amy on that message."

Even as digital technology seems to be on the cusp of the next big thing,"cc" is here to stay. The anachronism has survived 150 years, evolving from an industrial-era hand-copying tool into an indispensable feature of email etiquette, cementing its place in communication with one simple click.
