ITF have revamped their livescores page, and now offer direct links to livestreams.

This is great news for tennis fans, and should make sponsorship of ITF tournaments and players a much more exciting commercial proposition for potential sponsors. A really good move from the ITF, which I think should now lead to many more tournaments offering livestreams, therefore much more coverage and audience for ITF tennis, more income for ITF players, and just, WELL DONE!
