In the US CNN and Fox share a common framing of most issues, and have for many years now.
cnn was always the market leader in style
fox slowly changed to try and copy cnn
previously fox were total conspiracy channel style
meanwhile cnn have gradually moved toward a slightly more magazine style
the 2 have met in the middle
which is not surprising considering their population self identify as a 2 party ideological concept
i recall when fox tried to copy the massively popular morning tv style
what they realized is their audience lost interest as the day went on and felt it was old & tired and boring
so they changed it up a notch to try and entertain the different time zone moods
they really lost their way a few years back
and then youknowwho gave them free advertising for some reason
and they took that all the way to the bank focusing more on short attention span items and sudden quick changes
cnn seem to have a fairly good unique balance
anyone coming close to their style will be seen to be copying them and thus not 1st with news
and not reliable
currently the news industry in usa is still suffering from sell-out-mania
on the back of the media war between the usa and the uk
if i see it on cnn i know they believe it to be true
if i see it on fox i know they believe it might not be true at all(& they don't really care)
