When "Challe-Suppo" was launched by one department of the R&D Center in 2017, it was a small event attended by about 300 visitors. The next year, multiple departments participated, and from 2019, the activity scaled up with the participation of research bases around the world. The Grand Prize winners are awarded a right to pursue their themes in R&D projects.

In 2020, "Challe-Suppo" was held under the slogan "separated physically, connected by technology" amid the COVID-19 pandemic, becoming the first large-scale interactive event to be held in a full online format inside or outside the Sony Group. "Challe-Suppo" remained in a full online format in 2021 and provided an opportunity for people from across the globe to gather for open discussions. Keynote speeches were delivered in a multilingual live event not bound by the size of the venue, and a poster session was held in a 2D virtual space using avatars for interactive exchanges.

This made it possible for people who formerly had difficulty taking part in "Challe-Suppo" to join this activity. It is now a huge event that attracts over 1,800 participants from many parts of the world, including Japan, China, India, Germany, Belgium, and the U.S. where the R&D Center bases are located. "Challe-Suppo" is a place for everyone to present their ideas freely and achieve self-realization through discussions, regardless of age, experience, title, and nationality.
