Servlets vs MVC frameworks

I very often come across this question of why we have got lots of web frameworks addressing the same or similar drawbacks. When looking deeply, I also have given thought on why JSP / Servlets is not being used after the other web frameworks (like Struts, Spring MVC etc) have shown their existence?
