Telemarketing is a form of marketing that involves having telephone operators call individuals or businesses in order to sell products or services. It is a type of direct marketing that can involve generating leads, sales and the making and taking of inbound and outbound calls. The first telemarketing calls were used by DialAmerica Marketing back in the 1950s and these used both inbound and outbound calls.
Today many telemarketing companies will use dialling systems in order to maximize the number of calls that can be made during any one day. Unfortunately many people regard this kind of marketing as a nuisance and will hang up on a telemarketer.
