The buzz is that CBS may “divorce” itself from anchor Katie Couric long before her contract expires in 2011. What went wrong?

Maybe it has nothing to do with Katie Couric or the fact that people are tuning out of television for their news. Maybe it comes down to a Viagra problem.

Watching the evening news — CBS or the other networks — we are bombarded with ads for one medical ailment ad after another. Penile erection, bladder control, constipation, bone loss, arthritis, diabetes. What kind of customer experience is this? Terrible. Erections and constipation happy messages while trying to make dinner, and maybe catch up on the news.

CBS, like most companies, has different silos responsible for different functions, and no one organization is looking at the customer’s experience. CBS News is responsible for Katie & Co., while the advertising group is bringing in the television dollars — and the Viagra ads.

In many retail companies, marketing is responsible for branding while operations oversees the stores, and never the two shall collaborate, often creating a mixed message and uneven customer experience. Similarly, customer service isn’t usually part of marketing, yet the customer service group often has more influence on customers than advertising, promotions, or pricing.

I hope CBS doesn’t put the blame for poor ratings on Katie Couric, a fine journalist. CBS has bigger issues; the customer’s experience matters more than the ad revenue. If the first is bad, the second will become disastrous.
