Holograms have yet to fully catch on, so making them is still expensive; one hologram video costs about 200 million won ($183,908) to make, which is two or three times more than a run-of-the-mill K-pop video.
SM has been experimenting with the holographic performances for more than a decade, although its first attempt to make H.O.T., a now-defunct boy band, a holographic debut failed in 1998.
NIK released its holographic images of Psy in World IT Show in COEX on May 23 before opening the exclusive theater for K-Pop Hologram-YG at Everland in Yongin, Gyeonggi Province this month. The Everland showcase will include the holographic performances of Psy’s “Gangnam Style” and “Gentleman” in July and add more holographic content from Big Bang and 2NE1 in September. After launching the Everland theater, it will establish some 20 venues for virtual performances of its K-pop singers in major theme parks or others in China, Hong Kong, Singapore, Thailand and North American and Europe by 2015.
