To honor the memory of Dongnang, the troupe was renamed Dongnang Repertory Company and continues to evolve through productions such as Birthday Party, The Odd Couple, and LUV. It opened new horizons for Korean theaters with the performances such as Chobun, Tae, Prince Hamyeol, and Chohon. Looking at 70 years of modern theater, Korean theater has hardly attained the global trend in which the arts are actively exchanged beyond borders. A tour in North America by the Dongnang Troupe was very significant in that it was a full-fledged overseas concert by the Korean theater. It was the first time a Korean theater was known on the international scene, as Duk-Hyung Yoo was invited to direct “á la main” to the first theater festival of the third world held in Manila, the Philippines, in 1971. In February 1974, Duk-Hyung Yoo also put Chobun on the stage of La MaMa Theatre, opening the doors to the world.
The Dongnang Repertory Company was invited to the World Theater Day at ITI headquarters in the spring of 1977, performing 10 times at La MaMa Theatre in New York and opening two workshops. A five-week roadshow was held in April across the Netherlands by the invitation of the Dutch government. The lengthy overseas performance ended only after performances in Los Angeles and Hawaii. The fanfare they received reconfirmed the status of the Dongnang Troupe.
Like a half century ago, when the Drama Center, Troupe and Seoul Institute of the Arts that were established by Dongnang and had already contributed to nurturing many actors and actresses as well as performance-related artists, the Institute leapt into its third period as the Dongnang Troupe performed Once Upon A Time, Whoa Hey Hwoyi in November 2009, based on the newly enhanced infrastructure of Art & Creation Center (ACC), Art & Technology Center (ATEC), and a school corporation TISPEN Entertainment.
