It would be unfair to single out foreign media as the only victims of The Onion's straight-faced wit, since the US media have fallen for its stories as well.
In 2010, Fox News' Fox Nation subsite treated an Onion story entitled "Frustrated Obama Sends Nation Rambling 75,000-Word E-Mail" as fact – as did numerous commenters on the story, according to Mediaite.
In 2004, MSNBC's Deborah Norville cited a new study as saying "58 percent of all the exercise done in America is broadcast on television. For instance, of the 3.5 billion sit-ups done during 2003, two million, 30,000 of them were on exercise shows on Lifetime or one of the ESPN channels." That study was, naturally, an Onion invention.
And The Onion continues to fool readers every day, as the Literally Unbelievable website reveals.
The Monitor is not presently aware of having treated a story from The Onion as factual. But The Onion's writers are quite clever, so the possibility can't be ruled out.
