CNBC is poised to tweak its prime-time programming. The New York Post reports that the financial news channel is working on a new roundtable show that might air in the 7 p.m. time slot now held by "The Kudlow Report.”

Producers are working on what’s described as a "rapid-fire talk show about stocks," the story notes. Possible personalities for the show could include CNBC’s Carl Quintanilla and Kayla Tausche.

The idea comes as prime-time viewership at CNBC has seen a drop-off in viewers during the first six months of 2013, as have the cable channel’s more popular segments that air during the day’s trading hours. Its average prime-time viewership fell to 91,000 viewers in the key 25-54 demo for the first half of the year, down from 94,000 a year earlier, the piece reports.

A rep for CNBC said, "We often experiment with different segments and formats that can be used almost any hour of the day and occasionally for specials during prime time as well."
