The UK (and possibly Ireland) is the only country in Europe where "digital" teletext has been successful to the point where the old teletext service could be closed down. That may be down to the fact that the British Isles used MHEG-5, which is nearly universal in DTT boxes, while the rest of Europe used MHP, that was usually not supported by STBs.
There have been some "teletext replacement" services run with MHP, but AIUI, most of them have been closed down as no viewers had the hardware needed to access them. The ones I've seen were never really as good as BBC Red Button. The only country where MHP has really taken off is Italy.
When the new millenium arrived, MHP was an unbelievably largely hyped thing here in Finland. It first came available to the wide public when the YLE24 service was launched in August '01. Amongst the main YLE24 channel, there were 5 simultaneous streams on a dedicated multiplex broadcasting raw news feeds and sports events from around the world.
On the same multiplex, there also were around-the-clock news from channels around the world. There were a total of eight news channels provided FTA to TV license payers, the first seven of those being BBC News 24/World, CNN, Sky News, ITN News Channel (IIRC later changed to Faux News), MSNBC, N24 from Germany and SVT24 from Sweden. The channels had Finnish subtitles and were broadcast on a one-minute delay - the eighth channel, Euronews, of course had multiple audio feeds instead of subtitles.
The text content of the service was called "super-teleteksti" (I guess I don't have to translate that
) and it offered the same sort of service as did the normal teletext, with the content being hyperlocalised for each and every transmitter. I think there was some kind of agreement between EBU broadcasters that allowed them to broadcast content from each other - at least here we had access to news from every EBU country in their own languages via super-teleteksti.
News junkies and anoraks of course responded well to this arrangement but the service was quietly shut down in the beginning of 2008. And that was the story of interactive TV in Finland. No, there was nothing on commercial channels - no, there was no other content. That's just it. MHP flopped
badly
. I have no idea why internet hasn't yet surpassed teletext - must be some kind of tradition on refusing to get acquainted with everything new.
And no, I am not sorry for the long post.
