100 episodes

In the U.S. television industry, 100 episodes is the traditional threshold for a television series to become viable for syndication. One hundred episodes are advantageous for stripped syndication because it allows for 20 weeks of weekday reruns (depending on the number of episodes produced once the program debuts in syndication) without repeating an episode, and such shows can be sold for higher per episode pricing.

Question: most television shows that reach 50 episodes minimum go into syndication and go into re-runs
Answer: no
