The conventional media of newspapers, radio and television lack

The conventional media of newspapers, radio and television lack face-to-face interaction.

These channels send a message one way to a large scattered audience without the sender and receiver meeting.

Because the two sides are physically apart, immediate personal feedback and mutual presence are missing.

These media are rich in contents rather than short of them, so absence of content is not the gap.

They command vast numbers of users, so a shortage of users does not describe their limitation.

They also possess wide distributive channels for reaching audiences, which again is not what they lack.
