Lockdown (2007): Lockdown (2007) was a professional wrestling pay-per-view (PPV) event produced by Total Nonstop Action Wrestling, which took place on April 15, 2007 at the Family Arena in Saint Charles, Missouri.  This was the second monthly pay-per-view, after Bound for Glory (2006), to be held outside Orlando, Florida.  It was the third annual event under the Lockdown chronology.  Eight professional wrestling matches were featured on the event's card.  In the tradition of Lockdown events, every match took place inside a steel structure with six sides, known as Six Sides of Steel.  It was the final TNA Wrestling pay-per-view event to officially feature National Wrestling Alliance championships (although the physical belts were used at the following Sacrifice event, the titles had been vacated by the NWA in the morning of the day of the event).

WWE No Way Out: No Way Out is a professional wrestling pay-per-view (PPV) event, produced by WWE, a professional wrestling promotion based in Connecticut.  The event was created in 1998 as an In Your House event in February of that year and in 2000 was made an annual pay-per-view event for WWE.  After the brand extension, the event was made exclusive to the SmackDown brand in 2004, being produced every February.  In April 2007, following WrestleMania 23, brand-exclusive pay-per-view events ceased being held, with the last of which being the SmackDown-exclusive No Way Out 2007.  After the event included two Elimination Chamber matches in 2008 and 2009, No Way Out was replaced by WWE Elimination Chamber the following year.  The name was revived for the June 2012 pay-per-view event.

WWE Extreme Rules: WWE Extreme Rules (simply known as Extreme Rules) is a professional wrestling event produced annually by WWE, a Connecticut-based promotion, and broadcast live and available only through pay-per-view (PPV) and the WWE Network.  The name of the event stems from most matches being contested under hardcore wrestling regulations; the defunct Extreme Championship Wrestling (ECW) promotion originally used the term to describe the regulations for all of its matches.  The event name was established in 2009; however, its theme began with its predecessor, One Night Stand, which was promoted in 2005 and 2006 as an ECW reunion show.  In 2007, WWE promoted the show as one of its own regular PPV events but kept the ECW concept of Extreme Rules matches.  In 2009, WWE renamed the One Night Stand event to WWE Extreme Rules.  The 2009 Extreme Rules event was noted by WWE to be a direct continuation of the One Night Stand chronology.  However, the 2010 event was later promoted as only the second event under a new chronology, one that is no longer a direct continuation of the One Night Stand events.  Starting in 2010, Extreme Rules was moved from June to late April/early May to replace Backlash as the post-WrestleMania pay-per-view event.  For 2013, the event was scheduled to take place in mid-May and replace Over the Limit, which was moved to October before being discontinued later that year and replaced by Battleground.  The event will return to the early June slot of WWE's pay-per-view calendar and will be a Raw-exclusive pay-per-view event.

Impact One Night Only: Impact: One Night Only is a series of professional wrestling events held by Impact Wrestling (formerly known as Total Nonstop Action Wrestling (TNA)).  Most events are taped and released later periodically as a three-hour pay-per-view broadcast.  The series began airing in April 2013, with new PPVs released on the first Friday of every month, except for the four months each year that each feature a live TNA pay-per-view event, with the exception of Hardcore Justice 2014 which was aired on January 10, 2014.  Every show is themed, e.g. around the X Division or tag team division.  Promoted as individual "specials", the events—unlike the live pay-per-view events—are not connected to the storylines featured on TNA's weekly television programming nor to each other, though later One Night Only events still incorporated storylines into matches and situations.  The concept was announced on January 11, 2013 by Impact President Dixie Carter as a part of a change to their pay-per-view programming.  Prior to the change, Impact Wrestling held live pay-per-view events monthly.  Jeremy Borash and Josh Mathews handle commentary duties.

It was the first WWF pay-per-view event to have a TV Parental Guidelines rating of TV-14.  The company would go on to give all of its pay-per-view events TV-14 ratings from this point through The Great American Bash 2008, with SummerSlam 2008 being the first of their pay-per-views to be rated TV-PG in over a decade.

The event was established in 2013, replacing No Way Out in the June slot of WWE's pay-per-view calendar.  In 2015, the event moved to the May slot of WWE's pay-per-view calendar.  WWE swapped dates between Payback and Extreme Rules in 2016, with Payback taking place on May 1 and Extreme Rules taking place on May 22; making this event as a post-WrestleMania pay-per-view event.  In 2017, the event moved to the late April slot of WWE's pay-per-view calendar and as a Raw-exclusive pay-per-view event.  However, following the 2017 WWE Superstar Shake-Up, this event also features an Interbrand matches between both Raw and SmackDown.
