Is Messi a "huge story"? I don't even know for what team he is playing. And as for Swift, I only know one of her songs name (pokerface, I guess?). As for Bieber, I never heard a single song and not interested to hear.

But in contrast, I have read lot of news about Durov.

Swift >> Messi >> Durov in popularity among the general population. Your unique interests may not generalize.

Depends on how you measure popularity. Monthly listeners to Swift songs, watchers of Messi matches? way below 950 mln.
