Gangnam-gu Office Internet SAT Broadcasting

What Gangnam-gu Office Internet SAT Broadcasting does

Gangnam-gu Office Internet SAT Broadcasting (강남인강, "Gangnam In-Gang") is a government-operated online learning platform established on June 1, 2004 by the Gangnam-gu Office, a district-level local government within Seoul Metropolitan City, Republic of Korea. It operates under Korea's constitutional right to education (Article 31) as a public initiative to reduce excessive private education (사교육) costs and provide equal educational access, serving middle and high school students (예비중1 through 고3/n수), lifelong learners preparing for the GED (검정고시), and international Korean-language learners nationwide. The platform is managed by Gangnam-gu's Smart Information Division (스마트정보과) within the Future Culture Bureau (미래문화국), with the Gangnam-gu Office Head serving as the legal representative.

The platform delivers approximately 20,000 lecture courses across all subjects (Korean, English, Mathematics, Science, Social Studies, vocational tracks) taught by 53 active instructors including current teachers and Daechi-dong (대치동) academy stars. Underlying technology comprises the Kollus Player video delivery platform (PC and native Android/iOS apps with offline download and 0.5X–2.0X playback speed control), an integrated Learning Management System with member portal, course enrollment, progress tracking, Q&A, and community features, the KT AICC AI chatbot for customer support, the Inicis payment gateway, and an AI Subtitle Service (auto-generated via speech recognition in 7 languages, applied to lectures produced from March 2026 onward). Content is structured in three progressive stages (concept mastery, advanced learning, problem solving) and aligned with major Korean textbook publishers.

The business model is a subsidized public subscription service with three pricing tiers: full membership (정회원) at 50,000 KRW (~$37 USD)/year for unlimited access to all lectures for 365 days, free associate membership (준회원) for non-video content, and free full access for welfare-eligible populations (national basic livelihood security recipients, national merit families, persons with disabilities, single-parent families, out-of-school youth, North Korean defectors) coordinated through municipal community centers. Group licenses (10% general discount, 40% Gangnam discount) are sold to 46+ joint-service-agreement partner government offices across all Korean provinces and the Government Employees Pension Service. Revenue also includes publisher content licensing arrangements. The platform has served 2.59 million cumulative students since 2004, with curriculum officially recognized for lifelong learning credits and GED exam exemptions through the Korea National Institute for Continuing Education (국가평생교육진흥원).
