No having to fax and retype, or putting floppy disks in the post where they get lost, damaged or arrive late. They can just comment on it and send it on to someone else. All in computer form, only printing out where necessary. Those mailing out to many organisations or branches can gain financially. With post, or even fax, you pay for each separate mailing or call.
Companies can also use the technology to form sectorial consortiums with greater commercial power.
Imagine someone trying to organise hotel accommodation for a large conference. At present, they have to telephone, fax or mail each hotel for room availability, facilities available etc. But what if the hotels get together and make this information available electronically on the Internet. Instantly they can see how many people each hotel can take on the days in question, who will need to stay at which place to have the required facilities and so on. Using the Internet, such a sectorial consortium could outbid individual hotels and those not using the system and gain trade in bulk.
