I'm Kryptonion

I've been wandering how long has Smallville been on for!!?? I've been on this little planet for about 15 years now and for as long as I can remember the young Clark, I did a little research and I found out it came on our shiny boxes in 2001 [: My best friend Nina is in love with Smallville or rather Tom welling, I swear that guy never ages!!!
In my research I also discovered that it ends in 2011 :'( this is where Nina thus breaks down in tears.
