In a telejournalism first, CNN announced Monday that from now on, all of its information will come from its own 24-hour, closed-circuit news channel, 'CNN-CNN.' 'The old method of gathering news, in which information was culled from the Associated Press, Reuters, our own reporters and the other 24-hour news channels, was inefficient and needlessly complicated,' CNN owner Ted Turner said. 'Now, we have a single, consolidated, in-house news source to which CNN can turn exclusively.' If the venture is successful, an airport version of CNN-CNN, CNN-CNN-Airport News, will be launched for traveling CNN reporters.
