So far video calling has not really caught on for everyday conversations. Rhodri Marsden looks at at why not and whether that is set to change.
Sometimes it matters what you look like. I'm off to a wedding in a few weeks and my outfit has been chosen, so I neither resemble an escaped convict nor threaten to upstage the bride. Later today I'll go to the supermarket wearing something more socially acceptable than my underpants, dressing gown and jandal combo. But what about video calls? Today I've already been urged three times by the world's biggest technology companies to talk to someone face-to-face via the web, but I look dreadful. More dreadful than usual. I haven't shaved, I'm wearing a T-shirt with the words "Sex Insect" on it, and I'm fat. Can we not speak on the phone instead?
We've shown a long-standing ambivalence towards video calling. The first ever demonstration was back in 1964 at the New York World Fair. American telecoms giant AT&T unveiled its Picturephone to gasps of astonishment, and it was stated - somewhat optimistically - that by 1980 a million people would be using it. But at its peak there were barely 500 subscribers across the whole of America. Subsequent incarnations were also stymied by dubious quality, excessive cost, and being sufficiently unpopular for there to be no friends to call using the thing even if you wanted to.
That's changed, of course. Video calls are now easy to make, crystal clear and cheap; mobile phones, tablets and laptops come with front-mounted cameras and microphones and we don't even have to strap on a headset that makes us look like the keyboard player in Level 42. Three industry giants are making a particularly concerted effort at the moment to persuade us that it's a great idea; Apple's Facetime, Google+ Hangouts and Facebook's new partnership Facing up to video calling
Mark Zuckerbergwith Skype position them all at the forefront of video communication. Facebook's Mark Zuckerberg, at the recent press launch, gushed, "It's awesome" - but will we adopt his enthusiasm? Research conducted last autumn showed that only 4 per cent of American internet users make regular video calls, and my own experience is similar to that of technology writer John Dvorak who noted: "Everyone I know has used it once." While the industry talks of "winds of change" and "a dramatic spike" in usage, many analysts believe widespread adoption is still years away.
