I know everyone, including myself, hates when telemarketers call. However for many small businesses, many industries and many new salesman it was a very necessary evil. I am lucky enough now to do B to B, but back in the day I got ton of business via telemarketing. My father who is a very very successful financial planner maintains that he got the lionshare of his business via telemarketing. While I think there are many factors that lead to the meltdown, I think taking away an identifiable stream of marketing, which is telemarketing contributed! Right now I believe 150 million homes are on the DNC, which equates to 95% of the population. Telemarketing as an industry and marketing option is DEAD. Big fish corporation can easily survive, but New and Small business can not! Yes we all hate telemarketing, but its a necessary evil for many businesses!
