Reaching a 50% digital share is music's equivalent to breaking the four-minute mile (though sustained profitability would be nice, too). And according to this IHT article, Atlantic Records claims over half its revenues now comes from digital. In contrast, parent company Warner Music Group's digital share in its most recent quarter was 27%.

Julie Greenwald, president of Atlantic Records, explained how the label did it. "It used to be that you could connect five dots and sell a million records. Now there are 20 dots you can connect to sell a million records."

Atlantic's digital revenues come from album and track downloads, ring tones, ring backs, satellite radio and subscription services.

I would have though Kid Rock's digital abstinence (which ended recently, though his catalog will be available only through Rhapsody through February) would have killed the label's digital share, but the label does have digital-friendly Death Cab for Cutie, and T.I.'s last album did well at digital and probably does great ring tone and ring back business. And there's a strong catalog that has a fading reach at brick-and-mortar retail but plenty of viability online.
