'Propaganda' is just a Latin gerundive meaning 'thing needing to be propagated'. The word was used in Germany and the Soviet Union, whereas the United Kingdom had a Ministry of Information in the World Wars doing the exact same things.
The Anglophone world has negative connotations for the word 'propaganda' purely because our enemies used that word more than us.
