Consumer Electronics Show: Super-slim TVs and 3D sets The 2012 International Consumer Electronics Show kicked off in Las Vegas on Tuesday, with stiff competition between leading television manufacturers. With a wider range of colours than liquid crystal models, Sony is showcasing its Crystal LED set, while rivals Samsung are creating a buzz with OLED (organic light-emitting diode) TVs that they plan to release to consumers. Smart internet-connected TVs and new offerings in 3D hardware and content were also attracting delegates to exhibits. While Samsung believes it has the right idea by offering smart TVs, Sony still insists that the picture quality is still of paramount importance. "We have been making content for decades and making TVs for decades," explained Shawn Cassidy, of Sony Marketing. No one walks into your house and says, 'Look at all those millions to one and all those hertz, they look great.' You look at your TV and say 'Wow! Look at that picture. That is what we bring, wow! Elsewhere at the show, which runs until Friday, celebrities such as 50 Cent were endorsing their own products. Signing autographs for fans, the rapper was helping to market his company's brand of wireless headphones that use a clear signal, rather than relying on bluetooth technology.
