How can I change the "content type" field name particularly in a view? I have a few content types on my Drupal instance. Eg. case study, forum topic etc.

I have built a view, to display few nodes and their content types.

In this view, I want to display the content type as case studies instead of case study, forum topics instead of forum topic.

I don't want to change the content type globally, but I want to change the content type only in this view.

Is there any hook that I can write to make this change?
Add a field to each of your content types, let's call it "Nickname" and enter the value you want to appear in your view, ie for Case Study enter "Case Studies". Now add Nickname to your View fields, and it should output the right text for each content type.
