LET IT ROLL, BABY, ROLL -- Ordinarily, when we think of media vehicles we think of media that are vehicles for delivering advertising or programming content. Increasingly, they are motorized vehicles - the kind people drive.

REMEMBER COLUMBIA BROADCASTING SYSTEM? NAH, WE DIDN'T THINK YOU WOULD -- Two e-mails sent in the past week send markedly different messages about the future of television. We only received one of them, while the other is lost forever.

A NOT SO BEAUTIFUL DAY IN THE NEIGHBORHOOD -- Normally, when we think about public television it conjures warm and fuzzy thoughts about TV with a nobler purpose. Something that is above the fray of crass commercial interests, or even worse: corrupt political interests.

LIKE A VIRGIN? YOU'LL LOVE THIS -- It's confessional time--again. We must disclose that even though we write a great deal about the business of television, we hardly ever get to watch the medium itself.

COVER STORY -- When American Business Media sent an e-mail last week advising members it had just published an update of its Code of Ethics for the editors and publishers of printed and online trade publications, we immediately requested a copy. And it's not just because we wanted to know how many of the rules we currently are violating.

OOPS! WE SUPPOSE THIS IS WHAT THEY INVENTED REWIND BUTTONS FOR -- Well, one thing you can say about MediaPost is that when we get it wrong, we get it really wrong. You know that story MediaDailyNews ran today about Magna Global USA's plan to factor VCR ratings out if its negotiations with the networks? Well, it turns out that's not what Magna plans to do at all.

MAYBE THEY SHOULD HAVE TRIED USING KEVLAR? -- Who among us hasn't regretted blasting an email message moments after pressing that darn "send" button? Confidentially, that's frequently the way the editors of MediaPost feel after transmitting some editions of "Real Media Riffs," but that has more to do with what we meant to send, not something we sent inadvertently. That's not what the research and PR team at CNN regrets this week after accidentally transmitting last week's Nielsen ratings press brief along with the personal back-and-forth comments of CNN executives included in the message.

ACTUALLY, IT PROVED TO BE A BIT UNRULY--Monday's Radio TV Research Council luncheon at the Yale Club in New York was supposed to help clarify the "Rules of Engagement," but from what we could tell, it seems like the industry might be better suited by circulating copies of "The Rules." That's the book that's supposed to help women find their significant others and get them to commit in a significant way.
