In recognition of the silver surfer phenomenon, April 23 was designated National Silver Surfer's day in the UK. Sometimes these 'national' days can seem like a hollow PR stunt although British Sausage Week will always appeal to our juvenile sense of humour. But Silver Surfer Day was part of a larger initiative designed to promote use of digital technologies to an older demographic, recognising their growing appetite for online know-how.

You could be forgiven for thinking that the older internet user treats the online world with a wary hesitation, but this is far from the truth. As this infographic demonstrates, granny and grandad have embraced all things online with just as much enthusiasm as the young folk.
