When it first
started in 1516, the mail service was just for the King, but a century later, it
was introduced as a public utility by King Charles I. During this romantic era,
the mail coaches were driven by handsomely-clad drivers who braved stormy
weather and highway robberies, similar to the age of cowboys and Indians in Wild
West.
From a mail coach
network, it progressed to a railway mail delivery system in the 1830s. Trains
were termed as "Traveling Post Offices" with onboard sorting
facilities, so traveling time could be used as processing time. Gradually,
airplanes took over and modernized the entire process. In fact, the Royal Mail
established the world's first airmail service in 1919 between London and Paris.
