What about the operators that were taken over by Island Fortitude? My memory is hazy, but they were somehow linked to King Long (or a subsidiary) and were an attempt to get their vehicles into the UK market? Took over quite a few smaller operators and quickly ran them into the ground.

Revealed: Criminal pasts of businessmen linked to collapsed bus firm's buyout
Sadly, that spelt the end for some long established firms such as Eddie Brown Coaches of Helperby who, coincidentally, had been one of the operators of the Ripon to York service mentioned elsewhere in that thread.
Where did Dales and District spring up from? I know they were a coach company. They seem to have cornered the market in that corner of N Yorkshire but they are picky. So North Yorkshire County Council (NYCC) buses are active in Ripon and Thirsk, and Little White Bus for Leyburn - Hawes and Richmond - Keld.
Dales and District are the bus operating arm of Proctors Coaches of Leeming Bar. They initially began competing on the 73 Northallerton to Bedale before benefitting from North Yorkshire CC splashing the cash on Rural Bus Challenge routes, initially taking the Wensleydale services when they were taken from Arriva and massively uplifted so there were hourly services from Northallerton to Hawes. They also gained stuff like the Richmond - Leyburn - Ripon that also replaced much more infrequent links, as well as gaining the tenders around Northalleton such as to Richmond, Leeming and the town routes.
A major expansion came when Arriva closed their Richmond depot in March 2006. As has been mentioned, Arriva retained only the main X26/X27/X28 route, with everything else that was tendered passing to D&D such as to Barnard Castle, Keld, town services, and two supplementary routes to Darlington, and also taking the Darlington to Northallerton and the Northallerton to Ripon routes, the latter commercially.
Fast forward and a combination of swingeing council cuts saw community minibuses and council welfare vehicles pick up certain routes, especially Northallerton and Richmond town routes, and those up the Dales, operating at lower costs either as just off-peak services between council welfare schools transport or crewed by volunteers.
Of the others, they have gone through a cycle of different operators (incl Arriva winning some back for a period) but in 2019, Hodgsons of Barnard Castle picked up most of the Richmond area tenders. They're left with just their core Bedale route, Northallerton to Ripon, Ripon to Richmond, and a few market day services operated by a single vehicle.
