Tufts University's Shir Appeal, University of Chicago's Rhythm and Jews, Binghamton University's Kaskeset, Ohio State University's Meshuganotes, Rutgers University's Kol Halayla, New York University's Ani V'Ata, University of California, Los Angeles's Jewkbox, and Yale University's Magevet are also gaining popularity across the U.S. Increased interest in modern a cappella (particularly collegiate a cappella) can be seen in the growth of awards such as the Contemporary A Cappella Recording Awards (overseen by the Contemporary A Cappella Society) and competitions such as the International Championship of Collegiate A Cappella for college groups and the Harmony Sweepstakes for all groups. In December 2009, a new television competition series called The Sing-Off aired on NBC. The show featured eight a cappella groups from the United States and Puerto Rico vying for the prize of $100,000 and a recording contract with Epic Records/Sony Music. The show was judged by Ben Folds, Shawn Stockman, and Nicole Scherzinger and was won by an all-male group from Puerto Rico called Nota. The show returned for a second, third, fourth, and fifth season, won by Committed, Pentatonix, Home Free, and The Melodores from Vanderbilt University respectively. Each year, hundreds of Collegiate a cappella groups submit their strongest songs in a competition to be on The Best of College A Cappella (BOCA), an album compilation of tracks from the best college a cappella groups around the world. The album is produced by Varsity Vocals – which also produces the International Championship of Collegiate A Cappella – and Deke Sharon. ). According to ethnomusicologist Joshua S. Dunchan, "BOCA carries considerable cache and respect within the field despite the appearance of other compilations in part, perhaps, because of its longevity and the prestige of the individuals behind it." Collegiate a cappella groups may also submit their tracks to Voices Only, a two-disc series released at the beginning of each school year. A Voices Only album has been released every year since 2005. In addition, from 2014 to 2019, female-identifying a cappella groups had the opportunity to send their strongest song tracks to the Women's A Cappella Association (WACA) for its annual best of women's a cappella album. WACA offered another medium for women's voices to receive recognition and released an album every year from 2014 to 2019, featuring female-identifying groups from across the United States. The Women's A Cappella Association hosted seven annual festivals in California before ending operations in 2019. South
