DVB-H seems to be a roller coaster technology, quite different adoption rates from country to country.
In Germany, DVB-H recently flopped as the business model of setting up a single DVB-H company that resells the services to mobile operators did not spark a lot of interest if not to say outright opposition from network operators and had to close down recently.
In Austria, DVB-H was introduced a year ago and according to this report (in German), A1 and 3-Austria have only been able to get a couple of thousand subscribers so far. DVB-H service costs 6 euros per month.
In Italy on the other hand, the same report says that DVB-H has attracted one million subscribers to date, some of the channels are available for free, and on average, subscribers watch for one hour a day. To me, one hour a day seems to be quite a bit much. But I can confirm, every now and then I see someone in the streets of Rome watching a football game on his DVB-H mobile, quite easy to spot the antenna sticking out and to hear the typical sound of a football game.
For those interested in further background info on mobile TV, here's another blog entry on mobile TV I've written earlier this year on DVB-T on mobiles (the big twin brother of DVB-H) and 1seg in Japan.
