It seems like Hollywood celebrities of old had longer careers than todays modern celebs. Maybe its because there were fewer of them? I mean, you didnt have television back in the 30s and 40s with infinite channels filled with shows or independent film companies, whereas today, time slots have to be filled and the entertainment beast has to be fed. Celebs of old also had fantastic PR people who made sure their allure did not get tarnished, nor did they have to deal with the hounds of paparazzi or social media. Today in Hollywood you can become washed up quite easily because of bad behavior, bad career moves, or just because the public becomes sick of you.
