When Jonah Lomu announced himself to the world at the Rugby World Cup some 20 years ago, he did so via that most traditional of mediums - the TV set.
He had no choice, really. Facebook, Reddit and YouTube were still 10 years away, Twitter 11 and Instagram 15. A vine was something grapes grew on and while the Graphics Interchange Format was eight years old, nobody knew a GIF would one day be a cool thing to embed in tweets and posts. Even the word 'blog' wasn't to be coined until 1999.
Lomu was rugby's first global superstar but he can't be blamed for failing to maximise his social-media profile because social media was a watercooler chat about the lead story in the paper.
But just say Jonah did what he did now, in a New Zealand-England semifinal at the 2015 World Cup (we'll ask you to suspend belief here and imagine the same players transplanted to a contemporary setting) with the country watching with a smartphone close at hand.
Here's what might happen*.
