Radio ads producers always try their best to produce a radio ad that dose not listen or sounds before it and have lot monotony. So they write a powerful jingle and custom ad that has the ability to get the attention of the listeners at once and can strike their attention from all other tasks for which they are busy. This ability of the jingles (a sound behind the voice in the radio ad) impresses a listener a lot and remains active for a long time in one's mind.
Another major advantage of radio advertising is that it is inexpensive to produce ads and to place them among the audience. This allows small business owners the luxury of placing advertisements on more than one station in a given market.
