So many TV programmes uses GoPros nowadays. Every outdoor show uses those. They just strap them in the weirdest places. 10 GoPros is something like 5000 euros and with that a fishing show can be sure that they will catch a nice angle when the big fish eats the lure.
Car shows? Just put one camera to every corner, on the roof, on the dash, trunk and what ever. Because why not?
Biking in some lifestyle/feelgood show? You can put couple cameras to every bike. When hiking everybody can have a camera.
No, the picture quality is not as good as with professional cameras, but few second clip from awesome angle with OK quality is better than great quality from bad angle.
