In the 21st century, radio spreads news, music, some discussion/conversation about random society issues... In our society, radio’s listeners have decreased, people rather prefer watching TV than listening to the radio, when they have the choice. Indeed, TV is more relaxing since it takes all your concentration for a while. However, the TV industry is not flexible as the radio one: TV channels are run by big private companies who choose the TV shows that people can watch. There are much more rules for having a TV program than a radio one. In other words, the TV industry takes longer to adapt to time.
However, radio can entertain your imagination more than you think. While listening to the radio you can imagine the scenes, and you are also more focused on what people say, because you don’t have images which distract you and influence your opinion. Nevertheless, most people are listening to the radio while doing something else at the same time to not waste time.

Radio is more trustworthy and accessible for everyone. Moreover, the fact that people who are working in the radio attract your interest just using their voice and nothing else is something very admiring.
So just some advice, if you want to be updated, you should rather turn on the radio than the TV!
