When radio first came, people said that no one would read newspapers anymore. They were wrong.
When TV first came, people said that no one would listen to the radio anymore. They were wrong.
When the first computer came, people said that no one would watch TV anymore. They were wrong.
So, when people said that radio would stop being important to people and no one would care anymore, they were still wrong, but they'd a point. As in radio not being considered seriously enough.
Therefore, World Radio Day 2020 is considered as important now as it was when it first was celebrated.
