Viewing numbers for the more articulate, knowledgeable commentators are actually pretty high though it's hard to determine how many of them are the domestic audience.
If you take the average terrestrial TV report, it can be a matter of a few minutes or in the case of the Iran conflict, maybe 5 minutes. The detail is often missed and the detail is critical to the overall picture.
I am amazed by the BBC reports on the Ukraine conflict for example, they paint a very different picture from the reality and the detail is missed, glaring issues within Russia haven't even been reported on. I'll only watch ITV news and Channel 4 news, Occasionally, I will watch BBC News 24 but I get thoroughly vexed by the anodyne reporting - I wish I didn't have to pay fort he TV license.
