International Business Times: May was yet another challenging month for the TV industry, with ratings down considerably across various broadcast and cable networks, according to new research from MoffettNathanson. Declines were seen in both prime-time and total-day viewership. Viacom led the race to the bottom, with ratings dropping 19 percent across its portfolio of cable networks, which include the youth-aimed MTV and Nickelodeon. In general, audiences have been gravitating toward on-demand programming or alternative platforms like Netflix or Hulu. But Viacom, with a younger target demographic, is feeling the effects of the paradigm shift even more than its competitors.
