Blake Shelton has been a coach on The Voice since the series' very first season on NBC, and there are a few clear reasons why the fans and the producers keep asking him to come back on the show. When Blake was introduced as a coach on The Voice, he was already a famous country singer, but not necessarily a household name across the United States yet. At the time, Blake was ed by Christina Aguilera, Adam Levine, and CeeLo Green, all of whom had bigger name recognition than he did. And yet, it was clear that Blake was the standout star of the cast since the very beginning.

There's no denying that The Voice has boosted Blake Shelton's career in a very significant way, but it is also worth noting that the hit NBC series wouldn't be what it has become without the country singer's involvement. Since being on the show, Blake has earned himself two #1 albums on the Billboard charts and plenty of hit songs on country radio. Meanwhile, The Voice has brought in very high ratings for NBC, has effectively eclipsed rival American Idol, and doesn't seem to be running out of steam anytime soon... even 20 seasons later.

All things considered, the fans fell in love with Blake Shelton for his hilariously strong confidence and his fantastic banter with other coaches on The Voice. Since the show first started, it also stood out to viewers how dedicated Blake has always been to his mentees. There were many times when Blake actually brought in his team of singers to his concerts, introduced them to influential people in the music industry, and provided his own platform to promote those contestants on the show. That might be one of the reasons why Team Blake singers have won the show seven times, which is the absolute record for any coach on NBC's The Voice.

Furthermore, Blake Shelton had a hilarious rivalry with co-star Adam Levine for many years on The Voice, up until the point when the Maroon 5 frontman left the series in season 16. In any case, Blake was able to develop an equally entertaining competition with fellow coach Kelly Clarkson once she was brought on board, and his banter with girlfriend-turned-fiancé Gwen Stefani on the show has also been hysterical for the fans to keep up with.

Blake is hungry for his eighth win on The Voice, but the competition is very stiff in season 20. Only time will tell if Blake has what it takes to bring it home once again, or if a newbie like Nick Jonas will be able to dethrone him this time around.
