WWE is adding more content to their “Vault” library next week. On Monday, May 7th, WWE Network is expected to add a number of episodes of Sunday Night Heat according to a recent report from WWE Network News.

The exact number of episodes to hit the Network on Monday is still unclear but its likely to follow the same pattern as WCW Thunder or WCW Saturday Night. A large chunk of episodes will be available immediately with the remaining to be released over time.

In total, Sunday Night Heat aired 513 episodes over the course of its 9-year run. While Heat was generally considered a B-show akin to Main Event these days, several big angles and matches took place on the show.

The most noteworthy episode of Heat was titled “Halftime Heat” and took place during halftime of Super Bowl XXXIII. Mankind defeated the Rock for the WWE Championship in an empty arena match that night. Not long after, however, Rock would regain the WWE Championship in time to walk into WrestleMania 15 as champion. He would lose the title to “Stone Cold” Steve Austin that night, however.

While episodes of Sunday Night Heat would air on Sundays, they would normally be filmed before Raw and air six days later. The final episode of Heat took place on May 30th, 2008. Rather than air on a network, however, the final addition of Heat aired exclusively on WWE.com. In many markets, the show was replaced by WWE Vintage from 2008 onward. In October 2000, the show briefly ran on MTV with Rebecca Budig and DJ Scribble serving as hosts.

While Sunday Night Heat does not have the best of reputations, several talented performers ran fun angles under-the-radar while on Heat. Tommy Dreamer, Raven, and D-Lo Brown all had storylines which were specifically confined to episodes of the show.
