The Internet has had a massive impact on the music industry, from the way users listen to music to how much artists get paid. One of the key disrupters has been YouTube, which turns 10 years old this week.
It has not just changed the way we listen to music -- but also how artists are discovered. Gone are the days of being scouted in a karaoke joint; now, young hopefuls dreaming of sold-out arenas take to the Web to showcase their talent.
CNBC takes a look at some of the biggest pop stars made by the Internet.

Perhaps one of the more controversial Internet pop sensations, Canada's Justin Bieber catapulted to fame after gaining popularity on YouTube.
The 21-year-old singer built his base of fans – known as "Beliebers" – after his mother started uploading videos of his singing to YouTube, starting with Bieber's rendition of an R&B song by pop singer Ne-Yo.
U.S. talent manager, Scooter Braun, stumbled across Bieber's videos, tracked the singer down and signed him to Raymond Braun Media Group, a music label owned by Braun and R&B star Usher.
In 2010, Bieber released his debut studio album "My World 2.0," which contained the hit song "Baby." The video was at the time the most-watched clip on YouTube.
Bieber has gained a reputation as a "bad boy" after several run-ins with the law and the media. In a survey by online real estate company Zillow last year, Bieber was named as the least desirable next-door-neighbor.

Another Canadian, Carly Rae Jepsen shot to fame in 2012 with her infectious single "Call Me Maybe" – one of those songs people secretly love.

"Call Me Maybe" has clocked over 670 million views on YouTube since it was posted in 2012. Although Jepsen has been quiet for the last couple of years, the Canadian singer recently released a single called "I Really Like You," featuring Hollywood superstar Tom Hanks in the video.

However, the band professed to not even know what MySpace was in a 2005 interview with Prefix Magazine.

Lily Allen is another artist who has MySpace to thank for her success.
The British singer found it tough at the beginning of her career in 2005 when she was signed to Regal Recordings.

Her following grew online and her label's ears perked up as media interest blossomed.
