A radio does not have the same advantages as other means of communication and entertainment such as the television and the Internet. It lacks visual appeal as no pictures emanate from a radio. A radio signal has limited strength.
Electrical power is needed at the source of transmission of the radio signal and at the reception point. A radio signal is often of poor quality when there is interference due to atmospheric conditions. People often perform other chores while listening to a radio and this makes the radio less engaging. Radios need more bandwidth and even then, the amount of data transmitted is limited.
In some areas such as mountains and valleys, the strength of a radio signal is often very weak making the radio almost useless.
