It seems to me that the first Internet Meme was hooking up Coke Machines to the Internet. It started when Coke Machines were connected to the Internet in 1982 at Carnegie Mellon University's School of Computer Science. The programmers at CMU wanted to check the Coke machine via the Net rather than walk up a few flight of stairs only to find an empty machine. Many colleges likes the idea and it was almost an Internet Status Symbol for Universities to hook their machines up to the Internet. Links about this are:
