Some entrepreneurs and businesses actually think business networking is really a more cost-effective supply of new customers than advertising or public relations. Business networking may be conducted in the someone's place of business community, or on the larger scale on the Internet. Social networks play an essential role for companies nowadays. Even law offices and oil companies have Facebook and Twitter so that you can attract more clients and then tell others there with what they do.

Robbins thinks: the team is made up of two or more than two, interaction and interdependence of individuals, according to certain rules combined together for a particular target group.
