LOS ANGELES (Reuters) - CNN apologized on Tuesday and offered a rare explanation from its control booth for a technical glitch many viewers failed to notice -- a large "X" the network flashed over Vice President Dick Cheney's face.
The wayward graphic, which CNN said lasted for about one-seventh of a second, appeared during the network's live coverage of Cheney's speech on Monday addressing critics of the Bush administration's conduct of the war in Iraq.
Word of the snafu quickly surfaced on the Internet, including still photos of the image posted by online columnist Matt Drudge, along with a story suggesting that some who saw the momentary "X" thought it might have been deliberate.
CNN, a unit of Time Warner Inc., later issued a mea culpa saying an investigation by senior management concluded "this was a technical malfunction, not an issue of operator error" and expressing regret for the incident.
The network followed up with a special on-air segment during its "CNN Live Today" broadcast, in which anchor Daryn Kagan joined the network's technical manager, Steve Alperin, in the control room to offer a fuller explanation.
The "X" image, a place-holding marker used by technicians to cue up graphics, is not supposed to be visible to viewers but was inadvertently projected onto the screen by a malfunction in a "switcher" device, they explained.
"So, for all the conspiracy theories out there," Kagan said, " ... that's not what this is about. It's a computer bug that people deal with everyday. It's just that ours was in front of millions of people."
A spokesman for the vice president said Cheney had no comment on the incident.
