Something I've been thinking about recently, given the current Ukraine war and how much information seems to come out very quickly, but even in this modern age some stuff is still secret or unclear because of military OPSEC concerns.

What I want to know is, while the second world war was going on and battles were being fought, how much did the general public in western countries like the UK actually know about events on the ground? For example, did they know about the events of D-day quickly afterwards, and if so how much? Would they hear about various battles immediately as they were in progress, or was stuff often held back until later? When the Germans surrendered in Stalingrad how quickly would people in the UK have known? Etc.

Basically I'm interested in a comparison between what media coverage of WW2 as it was happening would have been like, compared to modern news coverage of recent and existing wars.
