Arguably, if it weren't for the Today show, we might not know all that much about KT Tunstall. The NBC morning show, which reaches nearly 6 million people everyday, has the power to launch and sustain music careers, argues Billboard's Michael Paoletta. That's why you see everyone from Keith Urban to the American Idol kids on there. And if god hates you enough, you're gonna see Halle Berry booked on there, too.

"But there is a difference between who's watching these shows and what kind of artists have the most impact," Warner Bros. Records Executive Vice President Diarmuid Quinn says. "When artists like Michael Buble and Josh Groban appear, we see tangible and readable results, with an immediate impact on sales. The female audience is more reactive than the male demo."

Also, dudes aren't that into Michael Buble or Josh Groban. Unless they're the type of dudes reading Queerty. Which also explains tomorrow's performance by the cast of Broadway's Legally Blonde.
