Universal Music Group owns several major labels including Interscope Records, Island Records, Mercury Nashville, and Verve Records. Interscope and Island feature mainstream pop artists like Black Eyed Peas, Justin Bieber, and Mariah Carey who are heavily promoted through radio airplay, music videos, and word of mouth. In contrast, Mercury Nashville and Verve Records have more niche artists like Easton Corbin, Shania Twain, and jazz musicians who are promoted through online music databases and websites where fans can discover similar artists. While major label artists get widespread CD and merchandise production, niche artists rely more on digital downloads and occasional merchandise at live shows.
