Easy access to information on politics, government, and social issues brings news to the public faster than politicians or governments would like. this phenomenon is often referred to as
the global village
the cnn effect
political correctness
the global network

I'm not 100% sure, but in my view the answer should be: This phenomenon is often referred to as the CNN effect. CNN effect - is the effect of 24-hour informational resources have on political or economical climate. Such kinds of monitoring politics and government could cause changes in this area. For example, if resource focuses on economical situation in New York, investors pay more attention on this region.
