This “Late Show with David Letterman” marquee has seen lots of changes since the building opened as a theater in 1927. It became a CBS studio for live radio shows during the 1950s. Later, it was the home of The Ed Sullivan Show. This is where the Beatles made their U.S. debut in 1963. Other talk and game shows were also recorded here. David Letterman started in 1993. Since his retirement in 2015, The Late Show continue to be taped with Stephen Colbert at the Ed Sullivan Theater on Broadway in Manhattan.
