Nice to hear you picked Amiga as a research topic.
Your thesis title already frames the outcome of your research by claiming that Amiga revolutionised media. Your research has actually to show to what extent Amiga revolutionised media.
"Impact of Commodore Amiga on multimedia industry" or similar sounds better to me.
Perhaps you can start with a specific research question(s) rather than thesis title. What are you interested in?
+1, not an English major but this makes sense to me
