Abstract
The impact of TV Drama success on TV Rating and the channel promotion effectiveness is very high. The cultural and business impact has been also demonstrated through the Korean Wave. Therefore, the early prediction of the blockbuster success of TV Drama is very important from the strategic perspective of the media industry.
Previous studies have tried to predict the audience ratings and success of drama based on various methods. However, most of the studies have made simple predictions using intuitive methods such as the main actor and time zone. These studies have limitations in predicting. In this study, we propose a model for predicting the popularity of drama by analyzing the customer's viewing pattern based on various theories. This is not only a theoretical contribution but also has a contribution from the practical point of view that can be used in actual broadcasting companies.
In this study, we collected data of 280 TV mini-series dramas, broadcasted over the terrestrial channels for 10 years from 2003 to 2012. From the data, we selected the most highly ranked and the least highly ranked 45 TV drama and analyzed the viewing patterns of them by 11-step.
The various assumptions and conditions for modeling are based on existing studies, or by the opinions of actual broadcasters and by data mining techniques. Then, we developed a prediction model by measuring the viewing-time distance (difference) using Euclidean and Correlation method, which is termed in our study similarity (the sum of distance). Through the similarity measure, we predicted the success of dramas from the viewer’s initial viewing-time pattern distribution using 1~5 episodes. In order to confirm that the model is shaken according to the measurement method, various distance measurement methods were applied and the model was checked for its dryness. And when the model was established, we could make a more predictive model using a grid search Furthermore, we classified the viewers who had watched TV drama more than 70% of the total airtime as the “passionate viewer” when a new drama is broadcasted. Then we compared the drama’s passionate viewer percentage the most highly ranked and the least highly ranked dramas. So that we can determine the possibility of blockbuster TV mini-series. We find that the initial viewing-time pattern is the key factor for the prediction of blockbuster dramas. From our model, block-buster dramas were correctly classified with the 75.47% accuracy with the initial viewing-time pattern analysis.
This paper shows high prediction rate while suggesting audience rating method different from existing ones. Currently, broadcasters rely heavily on some famous actors called so-called star systems, so they are in more severe competition than ever due to rising production costs of broadcasting programs, long-term recession, aggressive investment in comprehensive programming channels and large corporations.
Everyone is in a financially difficult situation. The basic revenue model of these broadcasters is advertising, and the execution of advertising is based on audience rating as a basic index. In the drama, there is uncertainty in the drama market that it is difficult to forecast the demand due to the nature of the commodity, while the drama market has a high financial contribution in the success of various contents of the broadcasting company. Therefore, to minimize the risk of failure. Thus, by analyzing the distribution of the first-time viewing time, it can be a practical help to establish a response strategy (organization/ marketing/story change, etc.) of the related company. Also, in this paper, we found that the behavior of the audience is crucial to the success of the program. In this paper, we define TV viewing as a measure of how enthusiastically watching TV is watched. We can predict the success of the program successfully by calculating the loyalty of the customer with the hot blood. This way of calculating loyalty can also be used to calculate loyalty to various platforms. It can also be used for marketing programs such as highlights, script previews, making movies, characters, games, and other marketing projects.

Abstract
TV 드라마는 타 장르에 비해 시청률과 채널 홍보 효과가 매우 크며, 한류를 통해 산업적 효과와 문화적 영향력을 확인시켜줬다. 따라서, 이와 같은 드라마의 흥행 여부를 예측하는 일은 방송 관련 산업에서 매우 중요한부분임은 주지의 사실이다. 이를 위해서 본 연구에서는 2003년부터 2012년까지 10년간, 지상파 채널을 통해 방송된, 총 280개의 TV 미니시리즈 드라마를 분석하였다. 이들 드라마 중 평균 시청률 상위 45개, 하위 시청률 45 개를 선정하여 흥행 드라마의 시청시간 분포 (5%~100%, 11-Step) 모형을 만들었다. 이들 기준 모형과 신규 드라마의 시청시간 분포와의 이격 거리를 Euclidean/Correlation으로 측정한 유사도(Similarity)를 통해, 시청자의 초기(1~5회) 시청시간 분포로 신규 드라마의 성패 여부를 예측하는 모델을 만들었다. 또한 총 방송 시간 중 70% 이상 시청한 시청자를 열혈 시청층(이하 열혈층) 으로 분류하고, 상위/하위 드라마의 평균값과 비교하여, 신규드라마의 흥행여부를 판별할 수 있도록 설계하였다. 연구 결과 드라마의 초반 시청자 충성도(시청시간)는 드라마의 대흥행 여부를 예측하는데 중요한 요소임을 밝혔으며, 최대 75.47%의 확률로 대흥행 드라마의 탄생을 예측할 수 있었다.
