If we say radio it may seem outdated because of the technology that we have at his point in time. But what is the reality is that radio is still being used until this time and it is an effective tool. Even if the television is also present but there are advantages of radio that makes it still usable and essential to be used. Radio physically have improved over the years and the programs also have some changes but it is still one that is preferred.
One of the advantages of using the radio is that it can reach any audience at any time. When people are going to work, they could listen to the radio. When one is at home and has to do some chores but want to know the news, the radio is there. Radio also is portable or built-in in cars so they do not require any special treatment. Television is not that portable and even if many use the internet, not all can have the access to it.
That is why the radio is used also by companies to advertise their products or services. They can reach to as many audiences as possible that are not reached through technology. Radio also is very good as others who do not know to read can just listen to the radio and develop the story or scene in their mind. Even if there are many radio stations but there is a certain one that you can advertise that focus your targeted audience.
