In this respect, communication is more complex than telephony, but more efficient. But, because Internet communication can be more selective, it is dubbed a narrowcast form of communication. The messages can be tailored to specific users or receivers. Internet narrowcasting is not passive like broadcast technologies. It is fully interactive.
Users can be both senders and receivers.
Interactivity and multimedia make it richer than even television. Again, it is understandable why every commercial enterprise rushed to exert a presence on the Web. Some companies have re-created conventional retail catalog sales via the Web. Customers telephone catalog sales to order from the print catalog. Web buyers contact sales using forms.
