THE TIFFANY NETWORK IS NOW THE GERITOL NETWORK: “CBS has long been derided by rivals for attracting TV viewers considered too old for most advertisers to care about. Now the Murder, She Wrote generation is having the last laugh. Consumers aged 18 to 24, many strapped with college debt and living in their parents’ basements, aren’t forming households or starting families the way their predecessors did. Meanwhile, the youngest members of the massive Baby Boom generation turn 48 this year. And luxury car, financial-services, and pharmaceutical companies—three of CBS’s largest ad categories—want to reach them. . . . The selective nature of the economic slump also plays a role, says David Poltrack, chief research officer for CBS. The 45- to 64-year-old age group was least affected by the recession, according to U.S. Census data. That group’s 2010 median annual income of $60,700 was 2.1 percent lower than before the crisis. Those under 25 suffered a 9.7 percent decline, to $24,140.”
