     As is known to most of us all, the Grammy Award is the granddaddy of all music awards. It is to music

what Oscar is to the movies. The name "Grammy" is short for "gramophone (machine for reproducing music

and speech recorded on flat discs)", since the awards are shaped like those old-fashioned gramophones.

     Over the years Los Angeles and New York have played tug-of-war with the Grammy Awards show. What

about the result? The Grammy ceremony has been held 32 times in Los Angeles, 10 times in New York City,

and once in Nashville.

     In 1999, the show returned to Los Angeles (at the Shrine, with host Kelsey Grammer) thanks in large part

to a much-publicized feud between the show's organizers and New York Mayor Rudolph Giuliani. And the

Grammys didn't return to the Big Apple while Giuliani was still in office, eventually moving to Los Angeles's

Staples Center.

     But with Giuliani finally gone from City Hall, the Grammys returned to New York in 2003, at Madison

Square Garden.

     For 2004, the award show moved back to L.A., and has remained here. The 47th Annum Grammy Awards

show was held on Sunday, Feb. 13, 2005, at the Staples Center. The big winners for 2005 were the late Ray

Charles, U2, Alicia Keys, Norah Jones, Los Lonely Boys, Kanye West, Usher, John Mayer, Tim McGraw and

Maroon.

     For 2007, the annum Grammy Awards was held at the Staples Center in downtown L.A. The organizers

have decided to move the show back to Sunday again. In 2006, the show was held on Wednesday, Feb. 8.

CBS had moved the show from its usual Sunday spot to avoid competing with coverage of the Winter

Olympics.

     On Jan. 31, 2010, the Grammy Awards took place at the Staples Center in Los Angeles. Jamie Foxx and

T-Pain hit the stage with Hip-Hop pioneer Doug E. Fresh and legendary Guns-N-Roses guitarist, Slash.
