Some would say he's bigger than US President Barack Obama.
When Prime Minister John Key arrived at Facebook headquarters in San Jose today there was a surprise member of the line-up to greet him - founder of the $US80 billion Facebook empire, Mark Zuckerberg.
Zuckerberg was not on the official list and did not take part in a subsequent meeting between Key and Facebook executives but the pair exchanged words following his arrival.
Key, who is in the US for scheduled talks with President Barack Obama, has spent the past two days on the American west coast meeting with representatives of The Hobbit co-producer New Line Cinema and today with senior executives at Facebook and Google.
The meetings were arranged to talk about technology and innovation issues, a spokesman for Key said last week.
"[And the] areas of co-operation between these two important companies and New Zealand, and whether opportunities exist for investor interest in New Zealand."
"As a Government we are very focused on trying to lift New Zealand's technological capability. Google and Facebook represent real opportunities to keep and grow our on-line connections to the rest of the world."
Key's stop at the online heavyweights' headquarters was welcomed by Trade Me chief executive Jon MacDonald, who said "without doubt both Google and Facebook are very influential in shaping how we work and play".
