Idol group Rainbow was chosen to appear on the commercial for a drink.

June 7, Rainbow's agency DSP Media stated, "Recently, Rainbow signed an endorsement deal with a famous drink brand. For the first time since their debut, Rainbow will appear on a TV commercial."

It is the first time for all the members of Rainbow to be appearing in a TV commercial together. Rainbow was chosen to become the endorsement models when Kim Jae Kyung won first place on a contest for idol stars where they had to create a fresh logo.

A representative of the drink company stated, "They have many different qualities which will allow them to pull off a lot of different concepts."

Meanwhile, Rainbow released their new song "Sunshine" on June 4.
