First of all, I found this awesome site: io9. Seems to be an aggregate of sci-fi/future links from throughout the web.
io9 led me to this website, also awesome: Information is Beautiful.
The fellow from information is beautiful has created this image charting the time-travel of all the major time-travel themed television shows and movies (not counting Dr. Who cause that would be too messy).
I implore you to click here to see a larger version of the chart (which is, well beautiful) and read about what went into creating it.
The Timeline Chart.
