Synonym discussion
Sense: noun/1
All three alternatives describe a television or radio show that lasts a long time, but they differ in nuance. Long broadcast focuses on the act of transmission itself and is often used in formal news contexts ('the president's long broadcast to the nation'). Extended program suggests that the show has been deliberately made longer than its usual length, often for a special event. Marathon program is informal and colourful, suggesting an exceptionally long event that tests the audience's endurance, such as a charity telethon or a 24-hour music countdown. In everyday conversation, long program is the most neutral choice and the simplest for learners.

The compound long program (or long programme) came into use in the 20th century with the rise of broadcast media.
