A vast communications network runs beneath the ocean, carrying most international data through undersea cables. Despite advances in satellite communications, the ITU says more than 99 percent of global cross-border data flows through subsea systems. The cables transmit data as light through optical fibre, boosted by repeaters powered through conductors in the cable. Landing stations link subsea networks to domestic backbones. In South Korea, operators such as SK Broadband are expanding subsea links as AI data centres spread.

President Lee Jae-myung (이재명) said he will rationally reform regulations that no longer fit the times to strengthen the competitiveness of the broadcasting industry. In a congratulatory address read out at a Broadcasting Day event in Seoul, he praised broadcasters for driving K-content to the world’s centre and pledged to support autonomy and independence and build a “basic media society” guaranteeing participation, access and choice. Industry and parliamentary leaders also called for support.
