Google is in the early stages of growth and Twitter will justify its mooted large valuation, says Al Gore, the former US Vice President and an adviser to Google.
In an interview with The Telegraph, Gore dismissed recent concerns about slowing growth at Google, saying the search giant may seem like it has "been here forever", but it actually in the early stages of growth.
"The fact that the internet is in its early days guarantees that Google is also in its early days. There is a lot more growth to come at Google."
Gore, who is also a partner of Facebook and Twitter investor Kleiner, Perkins, Caufield & Byers, believes social media groups such as Twitter will live up to their large forecast valuations, even though some have not carved out clear business models.
"The Twitter business model is evolving rapidly and they do have a chance to monetise. The social media revolution is very real," he says. "And the markets are still buzzing after LinkedIn's IPO."
However, Gore says, TV is still the most important means of communication, with the internet constrained by poor connecivity and low bandwidth.
Gore said that the internet is still an inferior means of communication to TV, blaming poor connectivity and low broadband speeds in large parts of the developed world.
"The social media revolution is very real and in its early days. At some point in the future, the internet will become the prime means of communication in the world. But for now, TV dominates.
"In the US, people watch an average of five hours of TV a day. But the distributiuon of video is constrained by still evolving bandwidth."
