Washington, June 28 : Cable News Network (CNN) rating has drastically plummeted in the second quarter of this year, which is the lowest since 1991.

According to the New York Daily News, viewership for all three major Cable News channels from March 26 to June 22 was lower this year than in 2011.

In prime time, almost 446,000 viewers watched, with 129,000 in the 25-54 demographic that advertisers want.

Fox New Channel averaged 1.79 million primetime viewers, down just 1 percent from a year ago.

MSNBC averaged 689,000 total viewers, 13 percent below last year.

CNN, which generally tries to stake out the middle ground between right-leaning Fox and left-leaning MSNBC, has a long-established reputation and maintains strong international ratings.

The network also dropped to its lowest ratings as viewership for Piers Morgan at 9 pm and Anderson Cooper''s show at 8 pm declined drastically.

CNN''s numbers have been declining in the U. S. over recent years.

The network also recently cancelled the 6 p. m. John King show, and will soon extend Wolf Blitzer''s ''Situation Room'' for another hour.

The overall decline in cable news viewership has created mild concern in the business, because with the Republican primaries and now the general election heating up, this is generally considered prime time for news show with heavy political content. (ANI)
