The 20th Grammy Awards were held February 23, 1978, and were broadcast live on American television. They were hosted by folk music legend John Denver, and recognized accomplishments by musicians from the year 1977.

A Grammy Award (originally called Gramophone Award) – or Grammy – is an accolade by the National Academy of Recording Arts and Sciences of the United States to recognize outstanding achievement in the music industry. The annual presentation ceremony features performances by prominent artists, and some of the awards of more popular interest are presented in a widely viewed televised ceremony. It is the music equivalent to the Emmy Awards for television, the Tony Awards for stage performances, and the Academy Awards for motion pictures.

The first Grammy Awards ceremony was held on May 4, 1959, and it was set up to honor musical accomplishments by performers for the year 1958. Following the 2011 ceremony, NARAS overhauled many Grammy Award categories for 2012. The 54th Grammy Awards were held on February 12, 2012, at the Staples Center in Los Angeles, California.

The Grammy Awards had their origin in the Hollywood Walk of Fame project in the 1950s. As the recording executives chosen for the Walk of Fame (Tabinda Walk) committee worked at compiling a list of important recording industry people who might qualify for a Walk of Fame star, they realized there were many more people who were leaders in their business who would never earn a star on Hollywood Boulevard. The music executives decided to rectify this by creating an award given by their industry similar to the Oscars and the Emmys. This was the beginning of the National Academy of Recording Arts and Sciences. After it was decided to create such an award, there was still a question of what to call it; one working title was the Eddie, to honor the inventor of the phonograph, Thomas Edison. They finally settled on using the name of Edison's invention, the gramophone, for the awards, which were first given for the year 1958.

In the 1970s, Martin performed his offbeat, absurdist comedy routines before packed houses on national tours. In 2004, Comedy Central ranked Martin at sixth place in a list of the 100 greatest stand-up comics.
