Big Time Rush is a Nickelodeon Viacom Music Productions Band consisting of four members: Kendall Schmidt, James Maslow, Logan Henderson, and Carlos Pena Jr. Nickelodeon partnered with Columbia/Epic Label Group to produce the show, which is why music and instrumentals are incorporated throughout the series.

Big Time Rush's debut album, B.T.R., was released on October 11, 2010, via Sony/Columbia.[12] Their second full-length album, entitled Elevate, was released on November 21, 2011. Big Time Rush released their new song "If I Ruled the World" ft. Iyaz on iTunes July 22.[13] They have also released a number of new songs such as "Music Sounds Better With U" (feat. Mann), "Love Me Love Me", "You're Not Alone" and "Superstar". They also released three singles, "Paralyzed", "Blow Your Speakers" and "Epic" in 2012. Note: These songs were bonus tracks on their album "Elevate". "Blow Your Speakers" was the bonus track for iTunes, "Paralyzed" was the bonus track on Big Time Rush's Official Website.[14] Then, "Epic" was the bonus track on the U.K album version. They released their third CD, 24/Seven in the summer of 2013. Among the songs on the CD is "We Are" which won a Viewer's Choice award.

Nickelodeon partnered with Columbia/Epic Label Group to produce the show, which incorporates original music into the series.[15] Big Time Rush is one of the three Nickelodeon shows (the others are iCarly and Victorious) on which the cable network is partnering with the music group to promote music as well as shows.[11] The Los Angeles Times has been critical of the show's focus on music, noting:

There is a marketing angle, to be sure, the same crossing of the revenue streams that powers. "Big Time Rush," was developed with Sony Music specifically to move units.[8]

The closing credits of Nickelodeon airings of the show contain short clips of music videos for singles featured the series. Occasionally, full versions of the videos are featured.

The show incorporates wacky sound effects, some laugh-like noises, music, and editing cuts designed to make it more humorous to the intended demographic of viewers age 10 to 18;[8] this was also typical of creator Scott Fellows' previous work on Nickelodeon. However, the show does not have a laugh track. Big Time Rush made an appearance at the 2010 Kids' Choice Awards, the 2010 Teen Choice Award and performed at the 2011 Kids' Choice Awards. they also appeared in an episode of BrainSurge during the week of April 18–22, 2011. On November 24, 2011, the group performed the National Anthem at Cowboys Stadium for the Thanksgiving NFL game which was broadcast on CBS. Big Time Rush has released 3 albums, B.T.R, Elevate and 24Seven.

More singles were released in 2012. It is confirmed that Big Time Rush covered The Beatles songs in their new movie "Big Time Movie" which was released March 10, 2012.

They went on tour with Victoria Justice in 2013 on the Summer Break Tour. Their final tour was the Big Time Rush: Live World Tour in 2014 for the month of February.

The Palm Woods Hotel is the fictional hotel where the Big Time Rush boys, Mrs. Knight and Katie Knight live in Hollywood. It is the main setting for the series and plenty of the scenes take place in the Palm Woods lobby, park or pool as well as in the apartments and even the air ducts. It is commonly described as the home for the future famous since its residents are mostly aspiring actors/actresses, singers, models or performers such as Camille, Jo, the Jennifers, Lucy, Guitar Dude, Tyler and many others. It is run by the strict manager Mr. Bitters while Buddha Bob works as the janitor.

Rocque Records is the fictional record label owned by RCMCBT Global Net Sanyoid Corporation, Big Time Rush's label and the workplace of Gustavo Rocque and his assistant Kelly. It is supplied with songwriting and recording equipment and either Gustavo or the boys are seen producing there. It is the second most used setting of Big Time Rush stories. Names who worked with Rocque Records include Jordin Sparks. Its rival company is named Hawk Records. Rocque Records places include Gustavo's office, the bathroom and the recording studios (A and B). It is hinted that the record label is a parody of Interscope Records and Jive Records.

The apartment 2J is the Big Time Rush's apartment in the Palm Woods Hotel. It got its current form in Big Time Crib as it used to be simplistic, dirty and messy before. It features a swirly slide and latest home electronics and arcade games. It is claimed that Lindsay Lohan, Shia LeBeouf and Kanye West, all stayed in the apartment in the past. Its interior altered once more when James left Big Time Rush in Big Time Concert and moved into 2J, but it came back to normal soon. Other known apartments in the Palm Woods are the ones of Camille (4J), Jo (3I) and Lucy (2B).

Each episode begins with a pre-opening sequence, leading into the theme song. The opening theme is "Big Time Rush," and is presented as shots of characters mixed in with animated booklet pictures, scenes from various episodes, and graphic effects. As of season 2, Tanya Chisholm appears in the opening sequence as she has been added to the main cast.

A one-hour special preview (which serves as the series pilot and first episode) debuted on Nickelodeon on November 28, 2009, drawing an audience of 3.6 million viewers. The series' official premiere on January 18, 2010 (which followed the premiere of the iCarly special "iSaved Your Life"), was watched by a total of 6.8 million total viewers, Nickelodeon's highest-rated live-action series debut.[21]

The show received mixed reviews.[22] The Pittsburgh Post-Gazette stated the show was "Nick's attempt at building a Jonas Brothers-style pop band. It's Nick's answer to Disney Channel's 'JONAS,' albeit slightly less organic since 'Rush' doesn't feature siblings."[23] The Hartford Courant stated the series a "not so good" show "with their thin pop and unfunny comedies".[24] The Boston Globe stated the show as "one example in a growing list of kid shows selling showbiz fantasies to children. The genre is stronger than ever now and more fixated on the perks of the glamorous Hollywood lifestyle ... wish fulfillment at a time when tabloid dreams are ubiquitous."[16] DVD Talk had the following review of the Big Time Rush: Season 1, Volume 1 DVD. "It would be hard to craft a description engineered to be less interesting to me, and yet, as I plowed through this collection from the series' beginnings, I frequently found myself amended and entertained. Say what you will about Nickelodeon's teen programming, but they've got the art of making a solid sitcom down to a science."[25]
