Accession: 2464-80Identifier: 2464-80-I.


  • Creation: 1937-1953

Biographical Note

Joseph Giardina is the CTO/CEO of a radio frequency services company, DSI RF Systems, Inc., in Somerset, New Jersey. While working atop the Empire State Building in the 1980s he found a variety of abandoned RCA and NBC documents. Giardina donated some of these documents to the David Sarnoff Library.

The Empire State Building has had a transmitting antenna atop its structure since its construction was completed in 1931. The National Broadcasting Company (NBC) began experimental transmissions from the antenna in December of 1931 and by 1939 the first regular television broadcasts were introduced. Engineers from both RCA and NBC were involved in the research, testing, design, and construction of the Empire State Building broadcasting tower. In 1950 RCA Chairman David Sarnoff and New York City Mayor William O’Dwyer drove the first rivets into the base of the Empire State Building’s broadcast tower which allowed for the installation of multiple TV/FM antennas. Presently, Empire State Building Broadcasting offers technical facilities to the New York, New Jersey, and Connecticut designated market area for radio, television, and point-to-point broadcasting.

Scope and Content

The Joseph Giardina NBC collection is composed of correspondence, invoices, tests, schematics, and notes related to the broadcasting tower on top of the Empire State Building. The collection also contains correspondence and patents related to Armstrong v. Radio Corporation of America and National Broadcasting Company.
