There are photographers employed by newspapers and there are photojournalists who are freelancers and there are paparazzi.
All of them sell their images. None of them would exist without a ready market for their images. All are endangered.
Print newspapers are fading and paywall papers aren't yet proven.
Still PJ work is a harder sell today and probably more dangerous than ever.
Paparazzi? Anyone with an iPhone is a paparazzi-in-waiting.
