Alas, the article on Wikipedia is misguided (as many articles in the area of 
software development).  To begin with, MVC is rather a design pattern. 
Anyway, these are referenced:

<http://www.itu.dk/courses/VOP/E2005/VOP2005E/8_mvc_krasner_and_pope.pdf>
<http://blog.iandavis.com/2008/12/09/what-are-the-benefits-of-mvc/>

From the second link, a quote from GoF, Design Patterns:
<< MVC consists of three kinds of objects. The Model is the application 
object, the View is its screen presentation, and the Controller defines the 
way the user interface reacts to user input. Before MVC, user interface 
designs tended to lump these objects together. MVC decouples them to 
increase flexibility and reuse. >>

And to decrease complexity, as the very first reason for MVC was that of 
breaking circular dependencies.
