History

Good Data Corporation was established in 2013 as Cherry Picker Co., Ltd. The CEO, Won Soon-woo, serves as both CEO and Chief Researcher. He holds degrees from the Department of Journalism and Broadcasting and the Graduate School of Journalism at Korea University.
The company launched its key services starting in 2014, debuting its online public opinion analysis service, Good Data, alongside the beta version of its broadcast program analysis tool, Good Data M. The following year, the company announced the Korean TV program online public opinion evaluation index report and subsequently rebranded as Good Data Corporation. In 2015, it began publishing the Weekly Online TV Evaluation Report.
Between 2017 and 2022, Good Data was actively involved in public analysis projects. In 2017, it conducted a big data survey for the presidential election in collaboration with Maeil Business Newspaper. From 2017 to 2022, the company planned and operated the Korea Communications Commission's public site, RACOI. In 2019, it released search response survey results.
Major service expansions occurred from 2020 to 2021: Good Data launched NewsClee, a broadcast news clip response survey; began surveying OTT original programs; and opened the TVR platform. In 2021, it conducted an integrated TV-OTT K-content topicality survey and commenced the MakeNew joint AI learning data construction service.
In March 2022, the company announced FUNdex, a proprietary drama fun intensity index. That same year, Good Data collaborated with the Korean Advertising and PR Society for a seminar on "Development of FUNdex for Changes in Digital Media Viewing Environment and Rediscovery of Content Value," held on July 29, 2022. The FUNdex platform was officially opened in 2023. In December 2023, Good Data hosted the inaugural FUNdex Awards online. This award recognized outstanding dramas and non-drama programs from both television and OTT, with winners chosen solely based on data metrics from the platform.
In 2024, Good Data participated in the Busan Contents Market. That year, the 2024 FUNdex Awards were held for the first time as an offline ceremony at the Megazone Industry Academia Research Center Auditorium in Gwacheon Knowledge Information Town on December 19, 2024. The event was organized by Good Data Corporation and sponsored by Megazone Cloud and the advertising agency Pentacle. The ceremony was also broadcast live online, recording 1,000 concurrent viewers and achieving a cumulative 12,000 video views.
On May 22, 2025, Good Data signed a memorandum of understanding with the Korea Advertisers Association at The Plaza Hotel in Jung-gu, Seoul, focusing on the analysis of advertising effectiveness for content across TV and streaming services.

Online integrated issue power of K-content

Good Data's 'TV Popularity Evaluation' focused on analyzing online broadcast content-related posts. The survey targets programs on 5 terrestrial channels, 21 cable channels, and 4 comprehensive channels.
