I can very much see the concerns some have about GB News and its likely leanings/programming style.
That said I do think existing media may something to answer for and given some pundits a platform their contributions don't deserve. There are your fair share of 'shock jock'/'partisan talking heads'/'professional pundits' who channels must know add little insight to any discourse but are constantly wheeled out time and again by broadcasters - the likes of Isabel Oakeshott, Tom Harwood, Julia Hartley-Brewer, Claire Fox, Toby Young, Ash Sakhar, Owen Jones, Brendan O'Neill etc.
I get that channels need to fill their time and one of the easiest ways to do it is by having two guests on to 'debate' and these individuals get reaction and clicks but giving these sorts of personalities such a consistent platform leads to the sort of partisan atmosphere there is in politics these days. The existing news channels could and should be doing better.
Absolutely. The standard broadcast media have been utterly complicit in bigging up those unrepresentative, politically extreme 'pundits'. There seems to be an idea among TV producers that getting somebody from the hard-left and somebody from the hard-right is balance, despite the fact that the bell curve and all available data shows that their positions are outliers and the majority of the electorate are somewhere nearer the middle.
I suppose that part of it is predictability. All of those people you mention are completely predictable in their output - O'Neill to the point that his repetitiveness and predictable contrarianism has actually become a meme. If you are producing a TV debate show that has to give the appearance of balance, you want to know what is being said beforehand so you can have somebody else to contradict it. You don't want a bunch of sensible, intelligent people on who look at the evidence because there is a risk that they all might come to the same conclusion - then the evidence-free nutters will start whinging about a lack of balance. It's basically political programming by numbers.
And then you have the entertainment value - which is particularly clear on programmes like Question Time. They want ridiculous, extreme answers because that creates traction on social media. In fact, the broadcasters (unlike the one-sided newspapers) get to have it both ways as they get both the supporters and the opponents furiously responding to every clip.
I fully expect the usual crowd to be frequent appearers on GB News. I'm sure that many of the right-wingers will be presenters/regulars and the Corbynite outriders will be popping up to give the illusion of balance and to provide useful strawmen for their presenters to attack.
