The internet. Seriously. Talk to anyone in history and the invention of the internet or at least, global connectivity would be on every general's or kings or emperors list.

Outcomes of battles would have changed if the weather could have been checked in advance and the sway of the battle could have been viewed from satellite.
Go ask Julius Ceasar what he thinks of man walking on the moon. "And, what did you find? Rocks and higher jumping ability? Sheesh".
Then again, the Roman empire might have fallen over an addiction of LoLLions and /b/ orgies.
