The Wonga advert uses repetition of the brand name 34 times in 40 seconds to get it stuck in the listener's head. It features two voices, a high-pitched female voice saying "wonga" and a deep male voice repeating what she says. By using a catchy jingle at the beginning and end that people may find themselves singing, it aims to spread the brand through radio and word-of-mouth. The purpose is to raise brand awareness and promote sales through repetitive music and vocals.
