Thumbnail image for 2014-10-April-Melissa-Parrish.jpgMaybe it's a phone on a bus, or a tablet in a store or the laptop on your coffee table. Maybe you're wearing it on your wrist or over your eyes. Whatever it is, it knows who you are, where you are and the best way to reach you at any moment.

That may seem a little creepy until you consider you bought those devices to get helpful information, and in order to help you, they need to know the who-where-when-why of what you're all about. Of course, marketers want that info, too.

In the parlance of Melissa Parrish, this makes you "addressable," and it's transforming the very nature of marketing. About half of US online adults are now "always addressable," she says, and the number is rising oh-so rapidly.

Parrish, vice president and research director for the marketing leadership group of Forrester Research, was the lead author on a paper released this week that explored this phenomenon in fine detail.

It concluded with something radical: that companies actually need to make themselves useful to the audience instead of simply bombarding them with ads based on their personal attributes.  And it proscribed four main competencies needed to build that sense of utility.

CMSWire had a chat with Parrish at last week's Forrester Forum for Marketing Leaders, digging deeper into the themes of her noteworthy paper.

Murphy: I wanted to start by asking about the "always addressable" consumer. The more affluent the consumer, the more devices they seem to have. Is that a fair read of the situation?

Parrish: At the moment, it is. Household income is an indicator, one of the inputs that would predict addressability. But what we see is that as the price of ownership of devices decreases, and as the proliferation of connected devices increases, those income barriers are starting to go away, or at least become less important. Of course we do highlight that for marketers, because marketers are always looking for those consumers who have more buying power. The majority of always addressable customers today do have more buying power, so that is good news for them.

Murphy: With the Internet of Things coming, we're going to see a whole lot more connected devices. Will that follow the same pattern? Will it start in wealthier homes where you have more connected devices vs. a poorer person who may not be connected as much?

Parrish: I do think so, but I think it's because of the cost of the data services required to take advantage of the Internet of Things as opposed to the cost of the sensor-laden devices, which in some cases are not much more expensive than anything else. But I do think we will see that.

There's a commodity thing that has to happen. It's not just that the sensor-laden devices have to be cheaper to manufacture and cheaper to acquire. It's the ISPs, it's the Internet connectivity, it's the networks.

Murphy: For example, home security systems that let you check on whether your kids got home from school? That sounds like an upper-middle-classy kind of thing to me.

Parrish: It absolutely does. I think right now it is largely that, not least of all because it's comparatively expensive to install, it's a higher cost of ownership -- the services that go along with it are more expensive. And, in order to install it, you have to have a certain kind of connectivity to your home, and a certain kind of house. I live in a 100-year-old house. We're not getting home automation any time soon.
