Improbable Research - Table 1 provides a wealth of data worthy of comment. For example, the Lennon Theorem (1966) stated that The Beatles were “more popular than Jesus,” but this has not been true in any of the fame observations since 2001. A determination of whether the Lennon Theorem was true in 1966 is beyond the scope of this paper, but we can state that The Beatles are not currently more popular than Cristiano Ronaldo, who is 1.6 dBHa more famous. ... Of the nine ‘B’ List celebrities from 2005, one (John Lennon) has become an ‘A’ List celebrity and six have become ‘C’ List celebrities.
The sole ‘H’ List celebrity from 2005 to 2009, Elisabeth Scheneman, is now a Chief of Staff at the Pennsylvania Department of Health and has become a ‘G’ List celebrity.
Although it is simple to determine who the most famous is among a particular group of subjects, determining the most famous person of all is non-trivial. Schulman (2009) concluded that Barack Obama was the most famous person in the world in February 2009, and since his fame was greater than +15 dBHa (+16.3 dBHa), he was in a celebrity category by himself: an ‘A+’ List celebrity. This is no longer the case, as his fame has dropped to +12.1 dBHa over the past seven and a half years and he is now an ‘A’ List celebrity. In fact, he has been overtaken by one of the people seeking his job: Donald Trump now has a fame of +14.0 dBHa (for those who are curious, Hillary Clinton has a fame of +12.0 dBHa, Gary Johnson has a fame of –1.9 dBHa, Jill Stein has a fame of –2.7 dBHa, and Evan McMullin has a fame of –10.7 dBHa).
Donald Trump is the most famous person in the world, but he is not as famous as Barack Obama was in 2009.
