Back in 1945, commercial TV did not exist in most countries.
Radios were there, but few people in much of Asia, African and Latin American had access to them.
The literacy rate in much of Asia, Africa and Latin America was way lower than it is now. (The print media had little influence on those people.)
Many people got their "news" through words of mouth.
So I seriously doubt Hitler's global notoriety.
Today far greater share of population have access to the global media.
