Could be, but the counterpoint to that is that Hollywood spent the 1st 20 yrs or so replaying the war in our theaters and the TV in a way unlike the more recent experience. You literally can't count the number of WWII films that were released beginning during the war and right through the 50's and into the 60's. Plus TV series like 'Combat', 12 OClock High, Rat Patrol, Black Sheep Squadron (into the 70's there) and even send ups like 'McHales Navy' and 'Hogan's Heroes' For a couple of decades at least, you could never be very far from a WWII reference in the popular media.
But certainly the *immediacy* of media our access to current history has completely changed. In WWII there were weekly newsreels and no lack of radio, newspaper and magazine reportage from the field - it was just a few days/weeks (at least!) old before it was seen/heard. But was very present . Maybe the big difference is as you note - the internet preserves it all - and in that sense it keeps it all present tense. So today you can easily pull up or run into something from 20 yrs ago (or facebook pulls it up for you). By 1966 there was no way for anyone but an ambitious researcher to access a MovieTone newsreel from WWII.
