It really depends on what products/services are u selling. coz some channels are effective to one product/service doesn't they work the same for others.
eg. if you are selling Chinese Wok, the best way to boost sales is defintely roadshow, which is live demonstration at market, department stores or grocery stores. Thru interactive, you are show them how good is the wok and how durable it is.
But if you put it on TVC, the reality decreases, without interactive, people will have less interest on it.
