On November 15, 1867, the first stock ticker was unveiled in New 
York City. The advent of the ticker ultimately revolutionized the
stock market by making up-to-the-minute prices available to
investors around the country.

Prior to this development, information from the New York Stock Exchange, which has been around since 1792, traveled by mail
or messenger.

The ticker was the brainchild of Edward Calahan (1838-1912) who configured a telegraph machine to print stock quotes on streams
of paper tape (the same paper tape later used in ticker-tape
parades).

The United States launched a massive invasion of the Japanese
home island of Okinawa, with an initial landing of 60,000 soldiers
and marines, on this day in history, April 1, 1945.

The Battle of Okinawa proved the last major engagement of World
War II and the largest battle of the entire war in the Pacific Theater. 

Okinawa has been a critical strategic location for the United States Armed Forces since the Battle of Okinawa and the end of World
War II. The island was under American administration until 1972,
and today hosts around 26,000 US military personnel, about half
of the total complement of the United States Forces Japan,
spread among 32 bases and 48 training sites.

On September 2, 1969, America’s first automatic teller
machine (ATM) makes its public debut, dispensing
cash to customers at Chemical Bank in Rockville
Centre, New York. ATMs went on to revolutionize the
banking industry, eliminating the need to visit a bank
to conduct basic financial transactions.  

By the 1980s, these money machines had become
widely popular and handled many of the functions
previously performed by human tellers, such as
check deposits and  money transfers between
accounts. 

Today, ATMs are as indispensable to most people
as cell phones and e-mail.

for holding the USA patent to the automatic teller machine.
