Saw an interesting article from last week on Media Daily News which talks about how Nielsen is planning to track television ratings across multiple platforms and devices (TV at home, Internet, iPod, etc.), which is an answer to what's being called "the attention economy," i.e. someone wants to watch a TV show from their couch, or their desk at work, or else while riding the subway or in a plane. The plan is being called "Anytime, Anywhere Media Measurement," which reminds of that great song by The Who, "Anyway, Anyhow, Anywhere." It's a little more difficult for the TV stations, since their content is free and they get their revenue from advertising, but for publishers--if we can finally sell the consumer on some kind of versatile electronic format, with the right mix of freedom of use and digital rights management--then they can read the content anyway, anyhow, anywhere they want (er, as long as they pay for it first).
