Ratings Reflect Zahn's Technical Glitches

Paula Zahn's ratings were higher for the 15 minutes when her show suffered technical glitches than for the next 15 minutes when she was back on the air. Between 8 and 8:15pm—when thunderstorms interrupted the live feed twice and CNN aired seven minutes of commercials—Zahn earned a 0.6, with 516,000 households and 577,000 viewers. The show resumed at 8:12pm. But between 8:15 and 8:30pm, CNN dropped to a 0.5, with 468,000 households and 526,000 views. Her numbers improved during the second half of the show, rising to a 0.7, and she averaged 626,000 viewers for the hour. And the show still nearly doubled MSNBC's Countdown. (It averaged 341,000 viewers that hour.)
