This is perhaps too quick a question but I'm not sure on the meaning and after searching the net I've found nothing to give me confidence in any interpretation. Here is the text that prompted to ask this question:
活躍 means activity, apparently with a positive connotation of of flourishing or succeeding. While 話 has several meanings, in this case I believe it means story. Mashing the definitions together yields "activity story". That's nonsense in English of course. My question is what's an 'activity story"? A story with lots of action (in other words, an action story)? Or is it something else like "success story"?
