There have been a lot of buzz-worthy dramas so far this year, but which one captured the most interest in Korea? The Contents Power Index (CPI) rankings have been released for the first half of 2015, and they rank the top dramas so far this year. See which ones made the list!

The CPI rankings differ from pure ratings rankings because they measure overall interest in a series. The power index uses ratings in addition to other factors, like the number of articles written, internet search popularity, and activity on discussion boards to determine which shows are most popular. While there is a weekly CPI ranking, this report looks at all of the dramas that have aired on major networks or cable stations from January 2015 through June 2015.

Given the jam-packed cast and the experimental format, it comes as no surprise that Producer ranked #1 for the year so far. The power of the adorable Yoochun-Shin Se Kyung OTP in Sensory Couple pulled off a second place finish, and Pinocchio made a strong showing in third. Mask was one of only two currently airing dramas to make the list (alongside Orange Marmalade), pulling off an impressive 5th place ranking even though it's only halfway through its run. See the rest of the top 15 and their scores below:

1. KBS2 Producer 260.6
