The term, which appeared back in 1936 and at that time was the abbreviation of the name of the “SPiced hAM” meat canned trademark, which was supplied by American and allied troops during World War II. At the end of the war, it turned out that the supply of canned goods was still large and it was decided to conduct an advertising campaign with a view to selling them to the population. As a result, the word “SPAM” began to be found wherever possible: on the facades of buildings, in buses, newspapers, shop windows, etc.

The event from which the formation of the concept of “Spam” began was the distribution of messages in 1986 through the Usenet pre-Internet network with offers of easy money, which in fact was an advertisement for the financial pyramid. This case was successfully compared with advertising canned meat forty years ago, as a result of which the term “spam” was fixed and its mass use began.

Since that time "spam"name of the various types of mailings with advertising or any other information to Internet users without their consent and / or manifestation of personal interest in participating in this process.
