1) The radio advert team had to change the planned sound effects due to limitations in available effects. They changed the opening from bowling pins to a car driving to alter the setting. 2) The team worked well together recording voices without accents for their target teenage audience. Some giggling and loud noises occurred during recording but were not re-recorded. 3) Advertising techniques used to engage teenagers included repetition of the company name 'The A+H Food co.' and an upbeat jingle to get stuck in the listener's head.
