THE BELL TELEPHONE HOUR was seen on NBC-TV and ran until the spring
of 1968. The concert series was one of the first TV shows to be telecast
exclusively in color using a system perfected by RCA in 1954. It aired
every week on Friday evenings. 

RCA’s project SCORE (signal communications orbit relay equipment)
was the world’s first communications satellite. An Air Force Atlas  
inter-continental ballistic missile (ICBM) launched the satellite from
Cape Canaveral, Florida. The first voice broadcast from SCORE
was a message from President Dwight D. Eisenhower, shown in
the above photo.
