In MVC1 architecture there is no controller concept then why it is called as MVC architecture?

I think its not like ,there is no controller, but there is no good seperation between the model, view, controller like MVC2

MVC1 was a first generation approach that used JSP pages and the JavaBeans component
architecture to implement the MVC architecture for the Web.  HTTP
requests are sent to a JSP page that implements Controller logic and calls out to the Model
for data to update the View. This approach combines Controller and View functionality
within a JSP page and therefore breaks the MVC paradigm. MVC1 is appropriate for simple
development and prototyping. It is not, however, recommended for serious development.

In MVC1 there is controller concept, but view and model were not totally independent with each other or we can say teher was no proper seperation between two, as there was no proper framework designed.

In MVC1 architecture JSP page act as controller.But there is not enough sepration between Model, View, Controller.i.e. why we can say it is first version of MVC architecture.

There is MVC means Model, View & Controller, There is no MVC1 & MVC2, There is Model1 & Model2 Architecture

There is a controller in MVC1 architecture.
Controller in MVC1 architecture is implemented in jsp along with view of the page.
But the problem is there is no seperate controller in MVC1.
So burden of having both Controller and view in jsp is more.
JSP will implement both Controller and View components.
