>To be honest I do not find that answer, which is short enough to fit in a tweet, particularly helpful. For starters MVVM has been around longer than WPF or Silverlight and MVC has been around longer than the web, at least as most of us know it. Early 70s, right? In any case it does not explain the difference between the two.

>>>What is the difference between them? Should we have a preference? It would be easy to guess MVC, which dates from the 1970s, is out of it, but that might not be accurate. Is one on the rise and one on the wane or is it more complex than that?
