Michael Jackson being the 'most famous celebrity in history' is the biggest delusion of the pre-internet era. Back then, they just made up numbers like '4 billion fans' because nobody could actually track data. In reality, The Weeknd is objectively more famous globally today.
@Adrian_l899 Imagine unironically believing half the globe had access to international media in the 1980s. Those 'multiple sources' are urban legends. Streaming data today is real, 80s PR numbers are fairy tales.
