Which of the promotional tools you choose has a greater impact on the business.ie Advertising tv/ radio,flyers, publicity, online marketing?

I must say that impact of advertising electronically (tv,Radio) is much greater than any other tool because now a days people watch tv more frequently so it means more the audience you target in short interval plus the way you transform your product,service,message into commercial ads left a strong mark on minds.

It depends on the product or service u have & the target segmentation, some targets don't watch TV, some need other ways.
