For a long time, advertisements through various media channels have been used for promotion of brands. While advertisement and mass media promotions have their own appeal, are they really worth the high expenditures? For an effective mass media campaign, you have to spend a lot of money on shooting locations, actors, directors etc. But all this effort and money might not bring in the desired results, especially if you have a mid-scale business. The cost to reward ratio is not very high with advertisements. And when you have the option to recruit telemarketing call center services at a nominal rate, then it is simply not a justifiable option for medium level busineses.
