Sports photographers will often shoot JPG, especially if they need their camera to shoot as many frames per second as possible for as long as possible. Scott Kelby shoots JPGs at football games. And when you hear the 1Dx at a gymnastics event in full machine gun mode (12-14FPS), you know they're shooting JPG because it will take 180 continuous JPG images before slowing down, whereas it will only take 38 RAW images before it slows. And sports photogs don't have days to sift through and process hundreds of RAW files. They need to get their images out there.
