The biggest teams of the 80's were the Legion of Doom/Road Warriors, the British Bulldogs, the Hart Foundation, and Demolition. The Rockers deserve some credit as well, but considering there huge year were the early 90's I can't put thim on this list.

It is fairly amazing how the tag team division fades in and out over the years as well. The late 80's, early 90's were classic, the belts were just as important as the world titles in WCW, then WWF, and NWA. Then there were a few stale years before the eruption of the E&C Dynasty, the Hardy's, the Dudleys, the APA, and the New Age Outlaws in the late 90's. Since it has been a while since the tag division has been important, the next surge should happen soon (push the tag teams WWE, push the tag teams)...
