Now in direct competition with NBC's "The Tonight Show With Jay Leno" and CBS's "Late Show With David Letterman," ABC's "Jimmy Kimmel Live!" (which, until recently, aired at midnight) needs to keep the A-list guests and musical acts coming in order to attract much-coveted viewers. Kimmel seems to know as much; for the first show in his new time slot, "JKL!" will be welcoming Jennifer Aniston to the couch and No Doubt to the stage.
