Lee Young Ae had been LG Electronics brand ambassador since 2006. Since then, she had appeared in a series of ad campaign by LG, endorsing its whole suite of products from air-conditioners, laptop, TV, mobile phones & etc. A study conducted by the Korean advertising society last year had concluded that Lee Young Ae was 'the most persuasive female celebrity' and took over the crown from Jeon Ji Hyun (My Sassy Girfriend), who was the reigning advertising queen for the previous year. As such, she was the most sought after female celebrity for product endorsment.
