KBS 2TV's "Fight For My Way" topped a TV popularity index, taking over the lead that was occupied by Mnet's audition show "Produce 101" for nearly three months, data showed Tuesday.

Starring Park Seo-joon and Kim Ji-won, "Fight For My Way" scored 266.2 points on the Content Power Index (CPI), becoming the most popular TV program during June 19-25.

CPI, developed by entertainment company CJ E&M and Nielsen Korea, measures the popularity of TV shows based on the number of views of related news stories, online search tallies and buzz on social media.

The coming-of-age romantic comedy series centers around a group of four young adults, who say they have "third-rate lives" due to their mundane and mediocre lives but later push forward to realize their unfulfilled dreams.

Previously, the CPI index was led by the second season of "Produce 101" for 11 straight weeks. This year's male-exclusive show led to the formation of the project band Wanna One.

MBC TV's Saturday comedy shows "Infinite Challenge" came in second, adding two notches from last week, with 261.1 points, followed by the late night talk show "Radio Star" in third place, scoring 237 points.

"I Live Alone," MBC TV's reality television show, soared 22 pegs to finish fourth, with 229 points, while SBS TV's weekday series "Suspicious Partner" also climbed six steps from last week to rank fourth.

TvN's comedy show "Journey to the West 4" came in at sixth, trailed by "Dictionary of Useless General Knowledge," a reality-travel talk show on the same network, finishing seventh.

KBS 2TV's late night talk show "Happy Together" fell to eighth place, and the weekend music competition show "Immortal Songs" clocked in at ninth place. (Yonhap)
