The second hour refers to the second hour of the daily TYT show. With the exception of Friday power panels, Ana Kasparian will host the second hour along with Cenk Uygur. Topics typically remain more light hearted compared to The first hour and tends to relate to pop news.
Ana often complains that she hates production meetings because nobody seems to care about the second hour. Ana often will lecture Cenk about him starting late on the first hour, thus leading to The second hour running short.
