Received this information at our station from CBS this afternoon.
Kinda knew it was coming, but here is the official word (as usual, I cannot link to the affiliate's website, so the article below comes from a CBS press Release):
Power of 10 – Additional Episodes for Midseason
Press Release
CBS ORDERS SIX ADDITIONAL EPISODES OF
"POWER OF 10" FOR MIDSEASON
CBS has ordered six additional episodes of the hit new game show POWER OF 10, hosted by Drew Carey, for midseason.
POWER OF 10, which currently airs on Tuesdays (8:00-9:00 PM, ET/PT) and Wednesdays (8:00-9:00 PM, ET/PT), averages more than eight million viewers per broadcast and, for the last five broadcasts, it has won its time period in all key measures (homes, viewers, A18-49 and A25-54). On Tuesdays, POWER OF 10 has won its time period both weeks since it began airing on 8/28. On Wednesdays, it has won its time period three weeks in a row and four out of the six times it has aired.
POWER OF 10 will have its summer finale on a special night, Sunday, Sept. 23 (8:00-9:00 PM, ET/PT), so as not to conflict with the reality series premiere of KID NATION on Wednesday, Sept. 19.
