Hilarious: in the US, Larry Bird a guy who has not played ball in almost 30 years (!) is still way more popular than Larry Page. At least according to G trends.
The the OPs point however, Wikipedia is a special place.
How many people ever paid money to go watch Larry Page at work for a day? Corporate executives have wealth and power; let the ballplayers have the celebrity :)
It should be mentioned, there are also foods banned in the US that are legal in Europe... especially when only few and ambiguous studies are available - risk assignment might lead to different choices.
Most of the world does not care about basketball at all.
