In history, the way of communication is constantly upgrading. Before 1900, we could only send letters by writing letters and relying on others. This method was not only slow but dangerous. Then in 1900s, people invented some quicker ways. Communication, such as telegraph, allows people to pass and receive messages faster. For traditional methods of sending letters, telegraphs can be considered as an inter-generational development, because the inventors began to use electricity to transmit information, and then we will be modern. With a more convenient and quick way to communicate and deliver messages, such as wechat, we can receive information immediately, which is much faster than previous telegrams and traditional media. Therefore, the media is becoming faster and more convenient with the progress of the times, and it will not change our lives all the time.
