We first starting tracking coworking about 5 years ago. Back then it was a little known movement and few had heard of it. That's changed.
As the chart below shows, the number of Google search hits for the term "coworking" has increased substantially over the last few years.
Google search term hits are, at best, an imprecise way to measure awareness. But we've found it provides a directionally correct view of overall awareness levels and is useful for trend tracking.
