Blake Shelton has more than a little swagger when he eases into his red chair on NBC's The Voice. That's just one of the ways the show has changed him.

Sure, he was a confident man when he started the show 19 seasons and 10 years ago. But go no further than clips from the television show that got him the job to see how raw he was. When Shelton appeared on Clash of the Choirs in late 2007, he wasn't strutting or offering any version of his signature head point. Someone saw some potential in him, and frankly, that someone should get a big raise for it.

The video below finds nine ways Shelton has changed since he started The Voice, a bona fide hit show now set for Season 20 on March 1. A few are obvious and maybe even a little annoying if you're a die-hard fan of Miranda Lambert and/or Gwen Stefani. Don't worry, we're not getting all tabloidy. This Secret History of Country Music video shows how the television show shaped the man and his music, and it has done both. He also appears on fewer stages in 2021 than he did in 2011; or at least, he would if not for the pandemic. But some things haven't changed. See for yourself:

Physically, it's astonishing how little the seven-time team winner has changed. He grew his hair a little longer for a season or two, but for the most part, it's the same ol' Blake. He even dresses the same.

While the "Minimum Wage" singer has moved to Hollywood (part-time, at least), he hasn't given up his old country friends. Longtime BFF Craig Morgan will still share stories about them together, as will racer Elliot Sadler, two men who've been with him for nearly two decades. Dive into the above video to see how 10 years on television can change a man and then catch up on one of our most popular Secret History videos below. The new season is just starting.

Famous Singers from 'The Voice,' Then + Now

Ten years (and counting) made a huge difference for many of the most popular singers and stars of The VoiceBlake Shelton looks noticeably different, but so do some of country music's most memorable performers.

Winners like Cassadee Pope and Danielle Bradbery wore baby faces when they auditioned during their respective seasons. The same can be said for Morgan Wallen, a forgotten castmember from the show who's transformed more than anyone else on this list of The Voice stars then and now.
