Drone racing: How popular is it?

To enjoy the CBBC Newsround website at its best you will need to have JavaScript turned on.

So far the audience for drone-racing is fairly small, but it is becoming more popular.

Around 223,000 people watched the U.S. Drone Racing Nationals held in New York on the American TV channel, ESPN.

That's pretty tiny when you compare it to the millions of people who tune in to watch football matches.

However, it is about the same as the number of people who tune in to watch esports - big competitive video-gaming events, which are also becoming more popular.

The organisers are hoping that by bringing the sport to people's TV and tablets, it will encourage more people to take an interest in drone-racing in the UK.
