Re: Supplier
Well it's not universal but VM and its predecessors went for the areas with what they thought to be the best RoI. They never achieved market dominance in those areas which is why Ofcom never got too involved in their business. Most of those areas remain places with a high RoI for communication providers.
But would another CP want to go up against VM? Sure. Banbury near me had large parts of the town with VM and now everywhere has OR fibre. Same with Bicester a bit further south east. My small rural town never got VM but is now served by three separate cable networks. Swish, Gigaclear and lastly Openreach.
An interesting article about this here.
"As of January 2022, there were 10m likely 'Virgin solus' households. In other words, for roughly two-thirds of the households in Virgin's 16m footprint, it was the only supplier of Gigabit broadband. However, today, there are just 4.5m 'Virgin solus' premises, or less than one-third of Virgin's total. This points to the erosion of what was once a significant technical advantage for Virgin Media, where in many parts of the country it could offer far higher speeds than its rivals. "
I've always thought it to be a silly state of affairs. Technical solutions exist to allow the sharing of cables so why are businesses happy to overbuild? We don't overbuild water, sewage gas or electricity networks. But..apparently it makes sense to a lot of businesses.
Another somewhat drier article here which offers an explanation.
"This suggests that future competition is unlikely to be driven by connecting previously unserved homes. Instead, competition increasingly centres on customer switching, pricing pressure, service differentiation, and migration from legacy broadband technologies to full fibre."
