This was a turning point for Perfume in which their luck began to change. Although the sales for "Fan Service [sweet]" were not stellar, "Chocolate Disco" did catch the attention of an already well-established artist in the J-pop industry, Kimura Kaela. Kimura then played Perfume's music on her radio show consistently. While listening to Kimura's radio show, a commercial director named Akira Tomotsugi noticed Perfume and decided to use the three girls in an upcoming TV ad. On July 1, 2007, the commercial for NHK's national recycling campaign aired, featuring Perfume and a new song, "Polyrhythm". The commercial gave Perfume exposure they could have only dreamed of before. Subsequently, their next live show sold out, and Perfume became the first idol group to perform at the Summer Sonic Festival. On September 12, 2007, Perfume officially released their tenth single, "Polyrhythm". It reached number 4 on the Oricon daily single charts and climbed as high as number 7 on the weekly charts. This is noted as the beginning of Perfume's national fame. In 2008, the group followed up the success of "Polyrhythm" with "Baby Cruising Love / Macaroni". The single reached number 3 on the Oricon weekly charts and sold 50,000 copies. On April 16, 2008, Perfume released their first original album, Game. Game reached number 1 on the Oricon charts upon its release, making Perfume the first technopop group to achieve this since Yellow Magic Orchestra's Naughty Boys in 1983. At the time of the album's release, Perfume: Complete Best, "Polyrhythm", and "Baby Cruising Love / Macaroni" all re-entered the Oricon charts. The album went on to sell over 450,000 copies and is certified double platinum. After the album's release, Perfume First Tour Game was announced. The group toured 10 cities and sold out all tickets. On the final date of the tour, Perfume announced that they would be doing a 2-day show at the prestigious Nippon Budokan in November 2008 as well as the release date of their next single, "Love the World". 2008–2009: Triangle era "love the world" was released on July 9, 2008. It became the first technopop song ever to reach number 1 on the Oricon charts. In October 2008, the Perfume First Tour "GAME" DVD was announced. Upon its release, it beat prominent artists like Koda Kumi and Namie Amuro for the number 1 spot. Perfume then performed at Budokan for 2 days, November 6
