WWE Cyber Sunday (originally known as WWE Taboo Tuesday) was an annual professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE), a professional wrestling promotion based in Connecticut. Established in 2004, the event was originally called Taboo Tuesday as it was held on Tuesdays. In 2006, the event was moved to the more traditional Sunday night for PPVs and was renamed Cyber Sunday. The theme of the event was the ability for fans to vote on certain aspects of every match, using their personal computers and text messaging via mobile phones. The voting typically began in the middle of an episode of Raw a few weeks beforehand and ended during the pay-per-view, often moments before the match was slated to begin. Because of this, the event was billed as an "interactive pay-per-view."
During the event's first two years as Taboo Tuesday, it was held exclusively for wrestlers from the Raw brand. The 2006 event, which was the first held as Cyber Sunday, was also Raw-exclusive. Following WrestleMania 23 in 2007, however, brand-exclusive PPVs were discontinued, thus the events in 2007 and 2008 featured the Raw, SmackDown, and ECW brands. The event was discontinued and replaced by Bragging Rights in 2009. The event was revived as an NXT television special in 2022, but not branded as Taboo Tuesday.
