CNN effect
The CNN effect is a theory in political science and media studies which states that global television networks, in their modern ability to provide live, 24-hours news coverage from anywhere in the world, play a significant role in determining the actions policymakers take and the outcomes of events. == History == The 24-hour international television news channel CNN came to prominence for its use of live satellite broadcast, first in its coverage of the Space Shuttle Challenger disaster in 1986, and then in its coverage of the rescue of Jessica McClure, a Texan toddler who fell down a well in 1987.
