On how to predict trends and discover value, today's Internet queen Mary Meeker has taught many people a lesson. It was 2005, not long after the US Internet bubble burst at the end of the 20th century, and many people talked about the special database discoloration of the Internet. Mary Meeker, who was an Internet analyst at Morgan Stanley at the time, boldly gave a judgment - firmly optimistic about the Internet. And this point of view comes from her unusual observation angle and argumentation logic. After counting the content consumption and advertising revenue of print media, television, radio and the Internet, she found that consumers' attention and frequency of use of the Internet far exceeded the advertising returns generated by the industry at that time. In other words, Mary Meeker gave a scientific prediction using numbers instead of special database headshots: Internet advertising does have a huge potential waiting to be unleashed. Five years later, everyone found that the once "value depression" had indeed been re-evaluated. At the same time, the annual Internet trend report also revealed a message. In addition to the Internet, there is another type of content that needs to be repaired in value - Radio, that is, audio content including radio. Coincidentally, more than a decade later, a global giant music company made what could be called the special database biggest gamble since its inception – a strong entry into podcasting. And this originally started from an observation and question of its founder Daniel Ek: Consumers spend roughly the same amount of time on video as they do on audio. But the video market is about $1 trillion, while the combined music and broadcasting industries are worth about $100 billion.
