Who were the first USA citizens to develop an addiction to electronic media ?

General William Tecumseh Sherman is reported to have stayed long hours in the Louisville telegraph office soaking in military reports.
Sherman had what is now called Bipolar disease,
formerly called Manic Depressive disease,
where in his case the high energy “Manic” phase went on for much longer periods than his shorter Depressed periods.

President Abraham Lincoln ordered a telegraph room be created in the White House and did similar to Sherman.

As a Captain in the KY militia, John Hunt Morgan wanted to stay neutral and fight neither South or North states.
As a General for the CSA Calvary Morgan found that one of his troopers was a highly skilled telegraph operator who could quickly cut a telegraph line, install two Keys for Morse code going both directions, listen to both directions, then send false messages imitating other operators “pace” of dits and dashes convincingly.

This may be the first electronic media “Disinformation”
