The 2012 London Olympics come to an end on Sunday, concluding with the games' closing ceremony. London will hand over the Olympic Torch to the 2016 host, Rio de Janeiro. Artistic Director Kim Gavin will direct and highlight the success and highlights of London and the Olympic athletes these past two weeks. Over 4,100 performers will take part in the ceremony.

Athletes will march together and following tradition, will not march by nationality. Flagbearers with representatives from each country will begin the march in a single-file line.

The closing ceremonies begin at 4:00 p.m. ET, but will be tape-delayed on the East Coast at 7:00 p.m. ET. Unfortunately, the closing ceremonies will not be streamed live online by NBC, so U.S. viewers will have to wait patiently and avoid any potential spoilers.
