I know, its all bull mate, but it all started many years back when ADSL was being sold a fast broadband and then they needed a catchy new advertising name for the faster speeds after that and here we are with Fibre Optic Broadband...
In a few years it will probably get changed to Fibre Based broadband as Advertising for FTTH/P may increase, thought Openreach are looking to start rolling out even faster speeds using the same FTTc/dp in the coming years and thats going to need something to keep customers upgrading and ordering...
A lot of complaints have been made about the latest Virgin Media VIVID advertising, this is due to them calling there 100&200Mbps services "next generation fibre" and the "runt" 50Mbps being only standard fibre... however nothing has changed in the network but a configuration file....
This was reported to the ASA by myself and a couple others that I know of, but heard nothing yet... I suppose we need to let them have some time to pull the custom before its quietly pulled eh! :/
I would like to know though how the service you had in Spain was advertised when you got it and how it is advertised to this day... I'm sure there all the same, hell I bet some are kicking themselves that they didn't call one of the variations of ADSL Fibre Broadband as the exchange had a fibre hehe 
Thanks for that info.. the VIVID campaign I found truly astonishing.
As I see things, current technologies will just get stuck. Market saturation just means everyone who needs broadband already has it, and generates a lot of data at peak times. Meaning, last mile (from post/cabinet to the home) will only get more and more congested.
Virgin's network is just a mess. They just can't cope. Months and months of saturation unanswered and unresolved.
FTTC has speed limits .. there's only so much VDSL can do. And if they come up with something, cost might not be that different to upgrading that last mile to real FTTH.
In Spain things got interesting 10 years ago when Telefonica started rolling out FTTH. Until that point everything was just "ADSL", then "ADSL2+".
Each region had its own cable operator, and mergers and market consolidation lead to a few bigger companies, mainly Ono.
When Telefonica began FTTH, Ono announced "Ono Fibra Optica" just like all carriers do here. However the difference was that for some it was actually true!
Ono was banned from using that phrase and their marketing people found a loophole.. they now sell Ono Fibra.. because in Spanish you can argue that a fibre is a thread and a copper cable has threads of copper inside. Utterly ridiculous but basically Ono has made a niche market in those areas where Telefonica still can't reach with FTTH, so at the end everyone is happy and when Telefonica rolls out FTTH there's a mass migration of customers
