As any new technology comes to market, in IT we see the adoption of that technology, as long as it is adding value, become adopted faster and faster.
One of the real tricks to understand is, does the technology disrupt current processes or not. If they don't then you tend to have a much faster adoption rate. Here, I speak w/ Dave Vellante, @dvellante of Wikibon about this process and how it has evolved in the past.
