Hot switch

In broadcast programming, a hot switch or hotswitching is where the ending of one television show leads directly into the start of the show in the next time slot without a television commercial break. The concept is used to reduce the chances that people will switch to another TV network during the commercial break and allow the cold open of the new show to attract viewers; sometimes however, this will cause a commercial break right after the opening credits. It can also be called "seamless" broadcasting and is frequently used during television marathons and back-to-back airings of episodes of the same series.
