Technological Milestones

On May 24, 1844 (28th Congress), inventor Samuel Morse sent the first official telegraph from the Capitol to his partner in Baltimore, MD.

In 1880, the first telephone was installed in the House of Representatives lobby.

On February 8, 1922, President Warren G. Harding was the first person to use the newly installed public address system in the House of Representatives for a radio broadcast when he addressed a Joint Session of Congress in the House Chamber.

On December 19, 1922 (the 67th Congress), the first live radio broadcast of a House debate covered a constitutional amendment to abolish tax-exempt securities.

On January 3, 1947, the first live television broadcast from the House Chamber occurred during the opening session of the 80th Congress (1947–1949).

On January 23, 1973 (the 93rd Congress), the first electronic vote was held in the House Chamber. The vote was a 15 minute roll call vote of Members, which prior to the electronic system took on average 30 to 45 minutes.

On March 19, 1979, the House of Representatives inaugurated the first live televised proceedings of debate on the House Floor.  Both the Public Broadcasting System (PBS) and C-SPAN picked up the House feed and broadcast the House proceedings to the public.  The first Member to speak before the television cameras was Representative Albert Gore Jr. of Tennessee

Television Cameras in the House Chamber

For years, television cameras had covered special events in the House Chamber such as State of the Union Addresses and speeches by foreign dignitaries. It was not until the late 1970s, however, that House Floor debates were televised live.
