My earliest tennis memory is seeing Cliff Richard singing at Wimbledon during a rain delay, which I think was 1996.
Mostly I watched it to see how Tiger Tim was doing, and believe it or not I wasn't really aware of who Pete Sampras was (seriously). It wasn't until 2003 that I started watching more regularly, and it wasn't until 2006 that I was able to watch the whole tournament from start to finish, having finished my A-Levels about a week before it started.
I do remember a few matches from 2005 though, one of them I think was Federer's match against Kiefer, where Federer double faulted twice in a row through nerves. It could have been in the tiebreak because I remember it was on an important point.
And of course Murray's progress to the third round. I was so disappointed to see him lose to Nalbandian after being 2 sets to 0 up, but of course he was young then, and had already had a terrific tournament.
My first non Wimbledon tennis match was the 2008 French Open final. Considering how invincible Federer looked like to me up until that point, you can imagine how I must have felt...
2008 was when I really started watching all year round though. It was that year when I discovered live streaming sites on the internet.
So yeah, not as long as some of you guys certainly, but that memory from 1996 is such a nice one that I don't mind
