SEOUL, Jan. 9 (Yonhap) -- Entertainment-oriented cable channel tvN's new reality show "Coffee Friends" landed high on the weekly TV program chart in the week of the show's debut, data showed Wednesday.
The tvN program, which ran its first episode on Friday, earned a Content Power Index (CPI) score of 239.4 for the week of Dec. 31-Jan. 6.
The brand new show famously employed two heartthrobs, Son Ho-joon and Yoo Yeon-seok. Yoo cemented his presence with a breakout role in the wildly successful 2018 tvN drama series "Mr. Sunshine."
The new reality program was inspired by the two close friends' private charity project of the same title. The program reflects the continuing popularity of reality shows featuring gastronomy and celebrities in South Korea.
"Coffee Friends" follows the two young bachelors' attempt to build a brunch place out of a tangerine farm house on the scenic Jeju Island.
Other big-name entertainers, including Choi Ji-woo, are invited as guests of the Friday night show to add sparkle.
The weekly chart was topped by tvN drama series "Encounter," starring Song Hye-kyo and Park Bo-gum. The Wednesday-Thursday program depicts the journey of Cha Soo-hyun, a daughter of a high-profile politician who divorced her chaebol husband, to find her true love.
"Encounter" garnered a 269.4 CPI score and was followed by the SBS drama series "The Last Empress," which earned 252.6.
CPI, created by CJ E&M and Nielsen Korea, measures the level of popularity, social media presence and influence on consumer behavior of entertainment TV programs aired on the three major terrestrial networks -- MBC, SBS and KBS -- and the seven cable channels owned by CJ ENM, including tvN, Mnet and OCN, during prime time.
JTBC, another cable network that airs some highly popular entertainment shows and dramas, is not included in the measurement.
