Where does eminem's name come from?

Answer 1

It comes from his initials. his name is Marshall Bruce Mathers . and Marshall Mathers --> M&M, but that it doesn't give a conflict between the name from him and the chocolate M&M's (for avoid problems with the producter), he change it to Eminem --> his initials "M & M" (pronounced: "M and M", "M 'n' M", "Em(i)nem").

Answer 2

His real name is Marshall Mathers and his initials are M & M. M & M sounds like Eminem, so he spelt it that way instead of M & M.
