[London Lite]

Is the "HD" suffix mainly a UK thing? In the last year or so I've visited France and the USA, and they didn't seem to bother.

In France, ironically the only channel I observed with the suffix was BBC World News Europe HD (as it was then)!

It helps that France is largely HD for everything now, while the UK continues to allow sub-standard SD quality channels on DTT and a lack of will to upgrade Freeview to DVB-T2 for the SD only muxes.

Sky and Freesat still use SD as well, but hopefully when the BBC switch off their network SD channels, that will go some way for both FTA and pay tv to reduce the use of SD via satellite.
