I'm based in the UK and we only get live tennis through Sky Sports and Eurosprt. This means ourt coverage is pretty limited and I want live action every day.
Totally disagree, the coverage is not limited at all.
Every Masters event is covered very well by Sky. They have a live DC tie in Europe every WG round, as well as the final. Sky also have rights to a few other ATP events like Rotterdam, Nottingham and Bangkok. And USO of course.
Eurosport have signed a recent improved deal with WTA, so they don't show as much ATP as they used to, but they still show a fair amount. They have rights to AO and FO. They do a poor job with FO.
As far as the other tournaments go, this year Eurosport have had live coverage on most days from Doha, Marseille, Dubai, Valencia, 's-Hertogenbosch, Washington, New Haven, Vienna and Basel. They usually have Queens too, but I imagine UK viewers watch BBC's coverage rather than Eurosport's because ES has intermittent coverage.
If I recall, early in the season they showed the Murray matches v Hewitt and Roddick in San Jose. They had a very tiny bit of Palermo this year, they had more of it last year but WTA got in the way. I'm trying to think back to what they had last year that they didn't this year - Gstaad, Beijing.
All in all in the UK, I think we get a pretty good fill of Tennis (both ATP & WTA), although I wouldn't complain if there was more.
