Most South Koreans prefer to watch free video content with advertisements rather than paying for ad-free editions, a survey showed Sunday, with YouTube standing as the most-visited platform.

Around 94 percent of respondents said they enjoy free video content that comes with advertisements, the survey conducted by entertainment giant CJ E&M Corp. showed.

The study was conducted on 2,500 South Korean smartphone users aged from 15 to 49.

U.S. video-sharing platform YouTube stood as the most favored video platform on smartphones at 73.1 percent, trailed by Naver and Daum at 36.8 percent and 31.9 percent, respectively. Social network service Facebook held 26.7 percent.

Around 20.7 percent of the respondents said they like to watch free videos on smartphones as they have less advertisements compared to TVs.

The Korea Internet & Security Agency said the country's mobile advertisement market came to 832.9 billion won ($735 million) in 2014, growing two-fold on-year. The amount is anticipated to reach 1.05 trillion won this year. (Yonhap)
