Four million people tuned into the series premiere of USA Network's Burn Notice two weeks ago, and they held on to most of those viewers last week.

The Thursday night show has become a hit for USA. Most shows get big numbers for their premieres, because of lots of advertising and curiosity (*cough* Studio 60 *cough*), but don't hold on to them. It looks like fans like viewers like Burn Notice enough to give it another shot.
