Mark Rosenthal, the CEO of Al Gore's Current cable network, maintains that he is not concerned about a recent ratings report showing that Keith Olbermann's audience dropped nearly 30 percent in its second week. "Numbers are going to go up and they're going to go down," Rosenthal told Adweek magazine. "It's a marathon for us. And the show will build over time as more and more people continue to find Current, or continue to demand Current and cable operators continue to add it." He noted that competing cable networks are in 95 to 105 million homes, while Current, which is only six years old, is in about 60 million. "People forget that when they compare us to other networks," Rosenthal said. "We're not at distribution parity with the MSNBCs and virtually any other cable network out there."
