The company is additionally involved in licensing its intellectual property to companies to produce video games and action figures.
In Your House was a series of professional wrestling supercard events created by WWE, a professional wrestling promotion based in Connecticut. The events originally aired on pay-per-view (PPV) from May 1995 to February 1999 when the promotion was still called the World Wrestling Federation. In 2020, WWE revived In Your House for its developmental brand NXT. The 2020 event was streamed exclusively on the WWE Network with the 2021 event also available via traditional PPV and the livestreaming service Peacock, while the 2022 event was only available via WWE's livestreaming platforms. A total of 30 In Your House events were held between May 1995 and June 2022.
The WWE Cruiserweight Championship was a professional wrestling championship originally used in World Championship Wrestling (WCW) and later, World Wrestling Federation/Entertainment (WWF/WWE). It was contested by wrestlers under 225 lbs, billed as cruiserweights. Following the acquisition of WCW by the then-WWF in 2001, it became a WWF championship and replaced the WWF Light Heavyweight Championship. During the first WWE brand extension, it was the only title to be exclusive to the SmackDown! brand during its entire tenure.
The WWF Light Heavyweight Championship was a professional wrestling championship in the World Wrestling Federation promotion. The title was challenged by light heavyweights at a maximum weight of 215 lbs. It was created on March 26, 1981, for the Universal Wrestling Association (UWA) in a partnership between the WWF and UWA. On June 16, 1995, the title moved to Michinoku Pro Wrestling, but due to WWF's ownership of the title, it was returned to the WWF in 1997, the year which WWE recognizes as the beginning of the championship's lineage. The inaugural champion in UWA was Perro Aguayo, however, the WWE considers the inaugural champion to be Taka Michinoku, with his reign beginning on December 7, 1997. It was retired on March 8, 2002, with X-Pac as the final champion.
In professional wrestling, Cruiserweight is a weight class but also a term for a fast-paced, aerial-based style of performer. The term was first coined in the United States in 1996 by World Championship Wrestling. Prior to this, the terms "Light Heavyweight" and "Junior Heavyweight" were more commonly in use. The older term Junior Heavyweight is still favored in Japan, where many titles for lighter-weight competitors are called Junior Heavyweight titles. Prominent titles include New Japan Pro-Wrestling's IWGP Junior Heavyweight Championship, Pro Wrestling Noah's GHC Junior Heavyweight Championship, and All Japan Pro Wrestling's World Junior Heavyweight championships.
The WWE Draft is a process used by the American professional wrestling promotion WWE to refresh its rosters between the Raw and SmackDown brands when a brand extension is in effect. Wrestlers from the promotion's developmental brand NXT (2016–present) are also eligible to be drafted to Raw and SmackDown. Two of WWE's former brands, ECW (2006–2009) and 205 Live (2019), have also taken part in the draft during the promotion's various brand split periods.
Championship unification is the act of combining two or more separate professional wrestling championships into a single title.
The brand extension, also referred to as the brand split, is the separation of the American professional wrestling promotion WWE's roster of wrestlers into distinct divisions, or "brands". The promotion's wrestlers are assigned to a brand via the annual WWE Draft and exclusively perform on that brand's weekly television show, with some exceptions. Throughout its history, WWE has utilized the brand extension twice. The first brand split occurred from 2002 to 2011, while the ongoing second began in 2016.

The American professional wrestling promotion WWE has maintained several men's and women's tag team championships since Capitol Wrestling Corporation (CWC) seceded from the National Wrestling Alliance (NWA) in 1963 to become the World Wide Wrestling Federation (WWWF), which was later subjected to various name changes, including World Wrestling Federation (WWF) and World Wrestling Entertainment (WWE)—in April 2011, the company ceased using its full name and has since just been referred to as WWE. The first men's tag team title, the Northeast version of the NWA World Tag Team Championship, preceded the company's creation, as it was established in 1957 for CWC as a version of the NWA World Tag Team Championship, while the first women's tag team title, the WWF Women's Tag Team Championship, was established in 1983. Whenever the WWE brand extension has been implemented, separate tag team championships have been created or allocated for each brand.
