Formula One boss Bernie Ecclestone says the sport should replace its traditional grand prix format with two shorter races to appeal to younger fans.
The current format of the F1 weekend has been a point of debate in recent years, with Jenson Button recently suggesting shorter races after seeing how youngsters in Japan interacted with Pokemon Go. Ecclestone agrees this is one way to bring in a new generation of fans to the sport.
"People have a much shorter attention span and a lot of sports are looking at introducing shorter forms of their games," Ecclestone told the Sunday Times. "The television audiences went up for Brazil. We had a long race with the heavy rain and a couple of crashes but that meant we had two starts because of the red flags and people tuned in.
"We need to look at the traditional concept of one long race. Two 40-minute races with a 40-minute break in the middle when the drivers could be interviewed, cars worked on, would be attractive to viewers, the TV companies, the sponsors and advertisers would love it.
"Cars would qualify on a Saturday as usual for the first race and that would set the grid for the second. It would shake things up with lighter, faster cars."
F1 has recently been purchased by new owners, American company Liberty Media. Ecclestone thinks following the American model would be a good idea for F1 but wonders whether the sport is brave enough to adopt such radical alterations.
"But I don't know if we have the courage to change. Times change though and it is something we must look at. "All American sports have time-outs built in, mainly because American audiences can't concentrate. They grow up with everything in 15-minute segments on TV. People are the same everywhere now."
