Patrick Frater Asia Bureau Chief The free concert by K-pop sensation BTS in Busan, Korea, was viewed by upwards of 49 million people on Saturday. The free-of-charge “BTS ‘Yet to Come’ in Busan” concert was held in support of Busan’s bid to host the 2030 World Expo and represented an attempt to introduce the city and Korean culture to global audience. After a change of venue, the physical component was held at the city’s Asiad Main Stadium and attracted some 50,000 in-person guests. An additional 10,000 people in the city watched a live retransmission at the Busan Port, and a further 2,000 gathered in Haeundae, the tourist area that recently played host to the Busan International Film Festival.
