1860
Relay teams on horseback begin delivering the first post as part of the Pony Express. The private enterprise consisted of over 80 riders and hundreds of stations along the east-west routes that stretched from St. Joseph, Missouri and Sacramento, California. While the Pony Express only operated for 18 months, during that time it was a success. With the incorporation of the Overland Telegraph Company of California and the Pacific Telegraph Company of Nebraska, the Pony Express' days were numbered.
