Bang's stage name "Hitman" originated from this period, when g.o.d enjoyed success as one of the country's best-selling and most popular boy bands of the early 2000s, earning himself and Park a reputation as "hit makers".

[21][22][23] The success of the IPO, together with the commercial success of BTS that year, Bang's steps into diversification with apps like Weverse, and acquisitions of companies like Source Music and Pledis Entertainment among others, landed him on the 2020 edition of Variety's Variety500, an annual index of the 500 most influential business leaders in the global media industry.

[26][27] On July 1, following an organizational restructuring, Hybe Corporation announced Bang's resignation as CEO of the company to return his focus to music production.

[30] Bang was featured on the cover of the April 2022 issue of Time magazine, together with BTS, following the release of the outlet's annual list of the 100 Most Influential Companies in March.
