In April 2003, Herald Media and SK Telecom entered into an exclusive agreement to jointly launch "Korea Herald Premium Service," English-language education services for digital generations. The integrated service, which bundles educational content for various types of digital tools, brings together daily news content, audio versions of articles, and translations of content from The Korea Herald, as well as English-language instruction tutorials and testing services. All of the services can be accessed via the Internet, multimedia-capable mobile phones and other high-tech digital tools, such as PDAs and MP3 players. Developed and managed by Digital Herald Inc., "Korea Herald Premium Service" was successfully launched in June 2003.
