STAMFORD, Conn. — NBCUniversal’s TV and digital networks will show a record 6,755 hours of action during this summer’s Rio Olympics.

The previous high was 5,535 hours from the 2012 London Games.

The main NBC network will broadcast more than 260 hours, including the opening and closing ceremonies and extensive coverage of swimming, gymnastics and track and field, the company said Tuesday.

Rio is just one hour ahead of the United States’ Eastern time zone. The last Summer Games held in a time zone close to that of the U.S. was the 1996 Atlanta Olympics, when NBC was the only network airing events. It showed just 171 hours.
