TBF the country is probably lucky it was them who forced Murdoch to drop out, rather than the other way around.
I am sure Rupes wouldn’t have tolerated the state of GBN’s broadcasting, nor would he have infested it with cast-offs and chancers like Brazier and “Dewbs”. Even Wootton would have probably been told to remain under his rock at that rag rather than make a tit of himself on tv.
I think he'd have created a higher quality channel in terms of production but, unless he'd pursued a very different path, then he'd have come unstuck the minute he started casting around for people to fill the airways. You have a choice of either
Elder, once respected journalists who have a veneer of honesty but just come across as a bit bitter and ranty (Neil, McCoy, Stewart)
Clearly not very bright people who have realised a quick buck is to be made either as a direct puppet of Brexity lot (Grimes), or just by being a bell on twitter and print (Wooton etc)
Presenters who aren;'t getting many jobs anymore (Kirsty Gallagher)
and then slight outliers of just being odious, smug, and not very good at much (Andrew Doyle)
I'm not sure where he'd have actually got enough quality or watchable reporters to make it a long lasting channel.
