I was amazed when I learned that the pony express only existed for short while.
In operation for only 18 months between April 1860 and October 1861, the Pony Express nevertheless has become synonymous with the Old West.
The Pony Express was forced to close after the opening of the transcontinental telegraph. Telegraphs could be sent much faster and with less expense. In the end, the business venture that was the Pony Express lost a lot of money and became outdated fairly quickly.
