Disruptive Innovation by Clayton Christensen

I recently attended Gartner Group’s Annual Symposium held in Orlando, FL Oct 2011. At the symposium Clayton Christensen gave the best presentation/keynote that I have ever heard in the 12+ years that I have attended. He talked to the IT audience about Disruptive Innovation. This presentation is an hour long, but it is incredibly good and would highly recommend it:

World Cellphone Usage

4,100,000,000 number of mobile phone subscriptions in the world

over 60% of the people on earth have a mobile phone subscription service

in 50 different countries around the world, the number of cellphones per person exceeds 100%

(means more than one cellphone each)

not just places like Korea, but places like Gambia, wehre 1,000,000 people have access to a telephone, and only 50,000 of those are fixed landlines

90% of the world’s population will have access to a cell phone signal by the end of 2010

2,400,000,000 people using SMS (active users)

75% of the people who have data access on their phones

we’re not good at handling numbers, but 1,200,000,000 people use email, so twice as many using text messages

2.3 trillion text messages sent in 2008

20% growth curve over 2007
