CNN says "Piers Morgan Tonight" drew nearly 1.3 million viewers for its second airing.
It dropped sharply from Monday's premiere, when nearly 2.1 million viewers saw Morgan sitting down with Oprah Winfrey.
CNN said Wednesday that Tuesday's program built on the premiere's 25-to-54 demographic and led among cable-news talk shows at that hour. It featured an interview with radio jock Howard Stern.
In total viewers, the program ranked second, behind Fox News Channel's "Hannity" and slightly ahead of MSNBC's "The Rachel Maddow Show."
"Piers Morgan Tonight" airs weeknights on CNN at 9 p.m. Eastern.
CNN is owned by Time Warner.
