A strange little side quest
Between one round of Dora Save the Dog and the next, this is worth knowing: The Oregon Trail began in 1971 when three student teachers created a computer simulation to help Minnesota schoolchildren learn American history. That is only half the story. Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. That gives Dora Save the Dog a little more company than it first appears to have.
