[3] In August 2014, it was reported that the National Football League (NFL) had a shortlist of three potential acts for the Super Bowl XLIX halftime show, which were Coldplay, Katy Perry, and Rihanna.

[14] GlowMotion Technologies created 616 light globes, which appeared at the beginning of the performance, that were controlled by wireless means.

Her final costume was a Moschino Star Gown which he stated was a "full-on red carpet Barbie extravaganza".

[17] At the start of the halftime show, on-field participants held up light globes which created a bird's-eye view of Pepsi's logo.

[18] Perry entered the stadium riding atop a large, golden mechanical lion, opening her set with a performance of "Roar".

[19] She then proceeded to sing "Dark Horse", with 3D rendering on the field creating a chessboard visual where the turf constantly turned into "different shapes and sizes", as acrobats surrounded the singer.

[19][20] Rapper Missy Elliott subsequently appeared, performing her songs "Get Ur Freak On" and "Work It", while Perry played "hype-woman" beside her, having now changed once again into a custom Super Bowl 49 jersey.

[20] Chris Chase of USA Today stated that the performance "felt more like an Olympic Opening Ceremony", which he called a "major achievement".

[26] Josh Duboff of Vanity Fair stated that Perry "killed it" and "more than made up for" what she lacked in "dance moves or vocal precision" in "enthusiasm and ingenuity".

D'Addario stated that the only part of the performance that "fell flat" was the inclusion of "I Kissed a Girl" on the setlist, saying that Perry "shouldn't be relying on the cheap titillation of her first single" to get people's attention "this deep into her career".

[28] Amanda Michelle Steiner of People wrote: "Katy Perry fan or not, even the most cynical hater would have to admit that her Super Bowl performance on Sunday was a pop culture masterpiece.

[35] For the week ending February 1, 2015, Perry's discography registered a 92% sales gain in the United States, selling 121,000 albums and song downloads in total.

[36] During Perry's performance of "Teenage Dream" and "California Gurls", she was accompanied by several dancers in various beach-themed costumes, including two dressed as sharks.

[40][41] Various other elements of Perry's performance, such as her entrance on a mechanical lion, her costumes, and her exit on a flying star (which itself was compared to the former logo of NBC's PSA segments The More You Know), were all incorporated into humorous images on social media.

Hamilton stated that, "We were trying to work out how we could bring a beach scene to life and so one of the references that we looked at was that Scissor Sisters performance.

"[43] After the Super Bowl, lawyers for Perry began trying to obtain a copyright for Left Shark and also sought trademark protection.

Her team initiated litigation against an Orlando, Florida, artist named Fernando Sosa, who had been making 3-D figurines of Left Shark.
