Fundamentally, the internet removes the need for a person to conduct business (work, commerce) at the same location as their physical presence. The only reason this hasn't changed things in a fundamental way is that the old fogeys who want us to have a physical presence in the office where they can keep a beady eye on us need to die off.
This is very true - I am at home now, as are many of my staff who work from anywhere in the world in many different time zones.
With the internet, my small local business has now become (effectively) global and indeed my own small company sells on most continents via digital delivery.
I do have an office, but it is only as a base for occasional face to face meetings with permanent staff - I could not fit more than a few people in though.
The business model was unthinkable not so long ago and it is very much revolutionary. Any and every company's market (and every employee) is now able to sell their labour or goods worldwide - if they have some basic skills to use the fantastic opportunities available through simply having access to the internet.
