A week after strong numbers for the premiere week on Current TV, "Countdown with Keith Olbermann" took a ratings tumble in week two, reports Deadline.com.

The drop-off was significant, almost 30%, but some of that decline could be due to the July 4th weekend, according to the website.

For week two, in the key 25-54 demographic, "Countdown" averaged 93,000 viewers, down 29% from the previous week. The total number of viewers across all demos was 253,000, a decline of 28.5%.
