[11] Forbes stated that the notoriety of the song is another sign of the power of social media—specifically Twitter, Facebook, and Tumblr, in this instance—in the ability to create "overnight sensations".

[12][13] On February 10, 2021, to commemorate the song's tenth anniversary, Black released an official hyperpop remix produced by Dylan Brady of 100 gecs featuring 3OH!3, Big Freedia and Dorian Electra to more positive reviews.

According to Kelly, the payment covered one half or less of the production costs of the music video, and Black's family could have paid nothing in exchange for giving up all rights to the song.

According to Randy Lewis of the Los Angeles Times, the familiar structure contributes to the song's catchiness, making it what others have called an earworm.

[29] The co-writer and producer of "Friday", Clarence Jey, said about the song that "the concept we feel seems to have crossed a lot of boundaries, for the better or worse".

[35] Kevin Rutherford, a columnist for Billboard magazine, wrote, "Black's video for 'Friday' is one of those rare occurrences where even the most seasoned critics of Internet culture don't know where to begin.

From the singing straight out of Auto-Tuned hell to lyrics such as 'Tomorrow is Saturday/And Sunday comes afterwards/I don't want this weekend to end' and a hilariously bad rap about passing school buses, 'Friday' is something that simply must be seen and heard to be fully appreciated.

[39] Jim Edwards of BNET and Doug Gross of CNN both noted that the rap break from the considerably older rapper was "creepy".

"[31] Rolling Stone's Perpetua stated, "When you see this video, you immediately notice everything that it does wrong, but it actually gets a lot of things about pop music right, if just by accident.

"[45][46] Fellow teenage singer Miley Cyrus denied that she had criticized Black, saying "I am a fan" and that she sang Friday while driving.

[47] Simon Cowell praised Black, saying "'I love her [and] the fact that she's got so much publicity...People are so upset about the song, but I think it's hysterical...Anyone who can create this much controversy within a week, I want to meet.

[81][82] The video was shot on January 6, 2011[83] at Black's father's house with friends and family as extras, and requiring multiple takes over 12 hours.

Following its original release, it received 4,000 views, enough to please Black,[16] before comedian Michael J. Nelson's Twitter account and a Tosh.0 blog post, Songwriting Isn't for Everyone, drew attention to it on March 11, 2011, turning the video into a viral hit.

"[91] He also pointed out Black's intention to donate part of the profits from the song to school arts programs and relief efforts in Japan following the 2011 Tōhoku earthquake and tsunami.

[95] Not long after the "Friday" video went viral on YouTube, Black and her mother, Georgina Kelly, got into legal issues with ARK Music over rights to the song.

In a March 29, 2011, letter from Kelly's lawyer to ARK Music, it was alleged that ARK Music failed to fulfill the terms of their November 2010 agreement by not giving her the song and video's master recordings; by claiming Black as exclusively signed to the label; and by exploiting the song without permission, selling a "Friday" ringtone, for example.

ARK Music Factory responded by saying it was disappointed that Black decided to have the video pulled from YouTube despite the two parties being in "good faith negotiations".

Our use of the video has fully been authorized (as evidenced by four uninterrupted months and 160 million-plus viewings without objection) by both Ms. Black and the copyright holder.

[29] In June 2023, Entertainment Weekly reported on what it described as "an old meme" asserting that the song was secretly about the assassination of John F. Kennedy, which occurred on a Friday.

[100] The remix was released on February 10, 2021, and features vocals from crunkcore duo 3OH!3, New Orleans's "queen of bounce" Big Freedia, and alt-pop musician Dorian Electra, alongside production from Dylan Brady of 100 gecs.

"[102] Black's chiptune vocals are "glitched-out" and distorted to the point of being unrecognizable, accompanied by "a pounding bass kick and pixellated synth line" from Brady.

[101] Ben Jolley rated the remix four stars out of five in his review for NME, calling it a "serotonin-boosting rollercoaster ride" with "endless replay value".

[114][115] Jimmy Fallon released "Friday" as part of his 2012 Warner Records album, Blow Your Pants Off, which featured high-profile acts such as Paul McCartney and Bruce Springsteen.

[116] U.S.-born Chinese artist Dawen Wang (王大文; Wáng Dàwén) made a popular Mandarin cover of Rebecca Black's "Friday", which become a viral runaway hit in 2011.

[117] The song has also been covered in a recording by Richard Cheese,[118] and live in concerts by Todd Rundgren,[119] Odd Future,[120] Nick Jonas,[121] and Justin Bieber.

[126] During the concert of August 5 at the Nokia Theatre L.A. Live, Rebecca Black joined Perry onstage, performing the song as a duet.

[131] Gang Fight", released in March 2011, earned Bad Lip Reading a million hits and thousands of subscribers, with many spoofs soon following.

At the end of the video, "Terry" attempts to blame the excesses of the party (which had subsequently moved to her own house) on Black, only for her parents (Corey Feldman and Debbie Gibson) to disbelieve her.

[133] In November 2012, multiple outlets suggested that Nicole Westbrook was "the new Rebecca Black", on release of Patrice Wilson's "It's Thanksgiving".

[139] Rebecca performed "Friday" along with "My Moment", live in Suncorp Place, Sydney as a part of Telstra's 4G LTE network launch.
