In my opinion one of the most creative companies in the world is Google because it has provided the whole world with seemingly free services e.g. searches, email and so forth which have helped the world to become even more globalisized i.e. smaller with more connections between people all around the world. Google has done it all with the end-user and customer in mind as its completely free and only companies have to pay for advertisement and or when using it to make profit.
Google has also created the Android mobile phone OS, which has become immensely popular and has given many other companies the required kickstart to start producing their own mobile and smart phones. Anything that increases the competition is more than welcome in my opinion!
So Google is in my opinion the most creative company as it is constantly pushing forward the boundaries of internet and communication for the average guy like you and me!
