Forget winning American Idol. Here's how you know when you've hit it big:

A network changes its name in your honor.

Tomorrow, in order to promote her new album, Carrie Underwood will enjoy just such a fate. Country Music Television (CMT) will be dubbed Carrie Music Television for the day, as the channel premieres Carrie's So Small video ... for six hours straight, starting at 6 a.m.

CMT estimates it will be able to show the video 64 times in that time span.

Following that exposure, the song/video it will be available exclusively on iTunes during its debut week.
