These efforts began shortly after the emu became extinct, overused as the secret ingredient in Kentuckistan Fried Chicken. Not to be confused with cloning, since no sheep are involved. At first, the only successful emulation occurred in computer simulations, which looked and acted only somewhat like a real emu, and tasted more like pineapples. However, in 1992, Bill Gates introduced WinEmu, which sold more than six copies.
