Twitter celebrates 5th Birthday, reveals stats

Twitter is celebrating it’s 5th birthday this week and have revealed some interesting statistics on how their social network is growing. It’s actually hard to believe Twitter has been going for 5 years.

Adoption was a little slow in Australia, as in 2009 in the service really started to take off here.

Here are the stats Twitter released:

– It took 3 years, 2 months and 1 day to reach the 1 billionth tweet

– Now there are 1 billion tweets per week

– A year ago there was around 50 million tweets per day, now there are 140 million tweets per day

– When Michael Jackson died there were 456 tweets per second. After New Years even in Japan there were 6939 tweets per second.

– Over the past year there has been a 182% increase in mobile access to Twitter

– Every day on average 460,000 new accounts are created

– Twitter now employs 400 staff worldwide.

According to Google Ad Planner statistics, Twitter has around 1 million unique Australian visitors (users) to the site every month. I don’t expect all of these users to specifically have registered accounts (eg. may just be browsing the site)
