Well,you followed basketball since you were very young.
In my country football is the #1 sport so I was basically forced to watch it.
Basketball was rarely on TV.
When I was a little bit older I started to like and follow basketball.
I even played for a local club.
Now it's my favorite sport,I often play it with my friends and I watch a lot of games.
Situation in the USA and Europe is very different.
You are able to watch a lot of basketball games while even if we want to watch it they are late at night and for a little kid it isn't appropriate to stay awake until 3 am.
I didn't watch NBA at all in the 90's so I decided to watch it now.
I'm pretty much obsessed with basketball now,especially with the NBA.
