Critics pan CNN's fake election holograms

The CNN hologram during the US presidential election bought the news network a wave of positive publicity.

But the fizz has gone out of the much-vaunted new technology as bloggers and hologram experts lined up today to point out that the holograms were, in fact, not really holograms.

PC Magazine blog, Gearlog, pointed out that "CNN's Holograms aren't Holograms: So Cut it Out."

"There was no live, glowing 3-D picture that people could walk around," wrote analyst Sascha Segan.

"The 'image' of Jessica Yellin and Wolf Blitzer standing in the same room existed only on TV screens."

The remarkable thing, he said, was that CNN could make the images look so real to viewers, while the presenters were speaking to thin air in the studio.

CNN billed its hologram technology as a world-first beaming in reporter Yellin and rapper Will.i.am from Chicago.

But, in the studio, presenter Wolf Flitzer was looking at just a red mark on the floor.
