|Fans in Spain watch F1 because of Fernando Alonso, not because of all that technology on the cars. Sports heroes matter.|
According to the F1 Broadcasting blog an average of 443,000 people in Spain watched the live broadcast of the Indy 500.
Compare to that, an average of 212,000 viewers in Spain watched the Monaco Grand Prix in which the retired-but-not-actually-retried Jenson Button subbed the race for Fernando Alonso. That means even though the races were at different times, the Indy 500, a traditionally American event, drew more interest in Spain this year than did F1’s biggest race.
The Spanish viewership of the Monaco race was also significantly down from 2016, during which F1 Broadcasting reports that 302,000 people in Spain watched the event. Viewership dropped by nearly a third this year, which is a huge portion of the rather small viewership.
Race fans don't watch races for the technology, they watch to see their heroes (in this case Fernando Alonso at the Indy 500) do incredible things behind the wheel
