NUVUE, the first cable television system in the Philippines, was set up in Baguio City by American expatriate Russel Swartley in 1969. Cable television became popular in the 1980s after the Marcos administration. Sky Cable, the largest cable television provider in the Philippines, began operations in 1992. Cable providers have proliferated since then, including Destiny Cable, Cablelink and some regional cable providers. In 2007, Sky Cable introduced the DigiBox, a set-top box that provides a digital television (DTV) signal for higher video quality and prevents illegal cable connections. In 2008, Sky Cable also broadcast the 37th Ryder Cup in high-definition television (HDTV). In 2009, Sky Cable became the first cable television service provider in the Philippines to broadcast the UAAP Games in high definition via the new SkyHD Cable TV service.
