In October 2009, the group signed a contract to make a commercial for Nonghyup Apples. They made the song "Apple Song" for the commercial. It was later included on the group's first studio album "Absolute First Album" under the name "Apple is A". In 2010, the group modeled for Mentholatum Korea, Tedin Water Parks, and Olympus cameras. T-ara was chosen to model for Tedin Waterpark again in 2011.
