Back in the days before photocopiers, word-processors and laser printers, if you wanted to send a letter to say, two people, rather than typing the same letter twice, you would feed two sheets of typing paper into the typewriter (foolscap of course!) with a sheet of carbon paper between them.
As you hammered away at the keys, the carbon paper would leave an imprint on the second sheet of paper and hey presto! Two copies.
Out of courtesy, or when you wanted one or both recipients to know the other had also received a copy, you would type cc. and the names of the recipients underneath.
I must admit however, that I had never encountered bcc.used prior to e-mail being introduced.
