Yeah man..Ind's 1.339 billion + 15 million outside of India (diaspora) + 200 million Pakistanis + 10-20 million others were invested in the match.

Obviously not all the populations were watching but most were, the hype is real due to many reasons:

1) Ind-Pak has had tensions for decades. They no longer compete in bilateral series against each other, in fact Ind even tried to convince the global cricket body to ban Pak from the world cup after their recent attack in India. So an Ind-Pak match is rare and happen only at global tournaments which is every 3-4 years.

2) Rich history. We've had many close matches in the past and high profile.

Obviously I'm biased but the celtics-lakers, barca-real madrid, arsenal-manU rivalries are a joke compared. Brazil-Arg maybe comes close.
