Katie Couric’s newsmaking interviews with the Republican vice presidential candidate, Sarah Palin, last week had only a slight impact on the ratings for her CBS newscast. But if the network could have added up all the other viewers the interviews (and its spoof) racked up, on places like CNN, YouTube and “Saturday Night Live,” Ms. Couric would surely have been more seen and talked about than in any week since she began her tenure as anchor.

Ms. Couric received a rush of attention for the two interviews, in which Ms. Palin, governor of Alaska, spoke haltingly on, among other topics, her state’s “narrow maritime border” with Russia. Clips turned up across the spectrum of television and Web sites.

The first interview last Wednesday, for example, has been viewed more than 1.4 million times on YouTube, while the parody of the interview on “SNL” was streamed more than 4 million times on NBC.com, viewed in full more than 600,000 times on YouTube and in shorter clips many more hundreds of thousands of times.

Still, the “CBS Evening News” gained only about 10 percent in audience from the previous week  and it was actually down from the same week the year before. The newscast averaged just under 6 million viewers for the week, up from 5.44 million the previous week. A year ago Ms. Couric’s program drew about 6.2 million viewers. (CBS was also a distant third last week behind ABC, which won with 8.07 million viewers, and NBC, with 7.98 million.)
