UPDATE: WWE is really boosting their classic wrestling content on the WWE Network. In addition to adding episodes of SMW, Mid-South Wrestling and NWA to the Vault section of the Network, there are now several 1988 episodes from the AWA available. More material is said to be on the way as well.
The episodes comprise the first AWA material on the Network outside of the documentary from the AWA DVD that WWE did a few years back.
ORIGINAL: The WWE Network has begun adding TV episodes from Smoky Mountain Wrestling and Mid-South Wrestling to its Vault Section. You can access them as a subscriber to the Network here.
At present there are five episodes of SMW, all from 1994. Mid-South Wrestling has three 1984 episodes.
