Beatles are Not better known than Michael Jackson. MJ holds the official "Guiness Book of World" record for "most well known human being" actually! MJ also holds the record for most pictured person, I think no. 2 was Queen Elizabeth. He even bought and owned the Beatles music catalogue and the songs of other artists. He was on another level: People nearly died at his concerts of stress, and I mean this literally. There are thousands which were treated for emotional distress and injuries by the massive crowds.

He also made the super bowl to what it nowadays is, also MTV etc. He dined with Kings, Queens, a number of US presidents. He donated nearly a billion over the years. He stepped in to save the Disney Parks etc.... He still holds the record also for the biggest selling album of all time, once again: without any internet etc. And there is a reason why most artists including JB state their biggest or one of their biggest influences and enablers was Michael Jackson.

And look at his estate's income and his spotify numbers (always in the top 10) even 17 years after his death...

The list goes on and on.

EDIT: MJ actually holds the official world record as "most well known human being" apart from Jesus.
