NBC
In 1993, NBC launched a 24-hour Spanish-language news channel serving Latin America (the second news channel serving that region overall, after Noticias ECO, and the first to broadcast 24 hours a day), Canal de Noticias NBC, which based its news schedule around the "wheel" format conceived at CNN. The channel, which was headquartered in the offices of the NBC News Channel affiliate news service in Charlotte, North Carolina, employed over 50 journalists to produce, write, anchor and provide technical services. Canal de Noticias NBC shut down in 1999 due to the channel's inability to generate sustainable advertising revenue.
