According to a report from AdAge [yahoo.com], every single network drama that aired on Tuesday night experienced a double-digit decline in ratings. And aside from a decent showing from The Muppets, the report relays that there have been few bright spots to the start of this year’s fall TV lineup.
...
All told, cumulative viewership during “Premiere Week”, as it’s called, is down 8% compared to the same period a year-ago. More worrisome for TV networks is that viewership from the highly sought-after 18-24 demographic is down 20% year over year, with male viewership within that demographic falling by 24%.
Males in the 18-24 demographic are the most coveted in advertising because that's when studies show brand preferences are formed. 24% is a catastrophic decline for TV.
