There is a famous movie line about football: football is round. This means that you never know what the result will be until the game is over. For example, Bayern vs Chelsea staged this famous saying in the European Super Cup last night. If it is replayed, you already know the result. If it is a pure appreciation process, it is better to watch the highlights. It's a psychological hint. When you are ready to watch the replay, your brain will make a conscious judgment that "the whole world has seen the result, only I don't know", which will reduce your appeal. On the contrary, when you watch the live broadcast, you may feel that "the whole world doesn't know the answer like me", which gives you an expectation. People will be more eager to know the unknown. For a long time, China's programs have only been broadcast live on those Spring Festival parties, military parades or some particularly important festivals and major events. So we all feel that live broadcast is a rare thing psychologically, and live programs must be good.
