Re: It's the semi finals of the Tier 1 event ... where are the fans?
I do think that there aren't many household names on the Tour for people in some countries to relate to. Apart from the Williams and possibly Sharapova there are no Everts, Capriati, Navratilova, Graf, Seles, Sabatini etc. It's a fact of reality that without a household name or big American/Western European names, the fan base in America and places like the UK diminishes. I was even surprised the other day when I mentioned Justine Henin to some friends - they had never heard of her! Never mind a lot of other players on the Tour. It may say a lot about the US and UK, but as I say, just a fact the Tour has to live with. For example Graf could still sell out all Wimbledon courts just by appearing on them for a few minutes - last year's appearance sold out in less than 5 minutes. The current semi-final line up couldn't.
Previous generations had big marquee names. Now it is Serena, Venus and possibly Maria/Kim. And none are in the semis.
