Seeking to distinguish itself in the highly competitive arena of TV news, Fox News Channel added a laugh track to its broadcast Monday. 'We found that viewers responded better to footage of flood-ravaged Texans and the mutilated bodies of ethnic Albanians when accompanied by canned laughter,' network president Allen Rudd said. 'This really seems to help viewers better digest and enjoy the oft-difficult content.' Depending on the success of the experiment, titillating whoops and 'whoahs' will be added to stories concerning the Clinton-Lewinsky scandal.
