When the FIFA circus rolls into Rio next year, it might just change the way we watch television. The final will be produced in 4K ultra-high definition. And if the World Cup has its usual uplifting effect on high-end TV sales, this could be the moment 4K starts to go mainstream. But what is 4K TV and why should we care?
Call me a Luddite but I remember the good old days. When you fancied someone and wanted to 'go out' with him or her you'd have to actually ask him or her out. i.e. pluck up the courage to talk to them in person. Yes, actually ask them verbally. This often meant you would soon have to meet their parents, or perhaps worse, their brothers and sisters. But things have changed.
