I like this piece in The Economist
on Facebook's audacious new advertising plan -- and not just because it
quotes me. Rather, the writer took seriously one of my long "there's
nothing new under the sun" disquisitions that most of my friends and
colleagues ignore. In this case, it's that today's social-networking
and -marketing phenomenon is not at all novel. Rather, it derives from
research done by two of the 20th Century's leading media theorists:
Paul Lazarsfeld and Elihu Katz.
Lazarsfeld (pictured at right) was a famed emigre sociologist from Germany and Katz his student at Columbia University when they did the work that led to their pioneering 1955 book,
Personal Influence.
The book challenged a reigning theory of media influence: that mass
media "work" directly, by injecting ideas into the minds of relatively
isolated people. That notion was -- and still is -- almost reflexively
accepted by anyone who has worked in or around media, marketing, and
advertising. "Our programs and ads," we believe, "forge peoples'
opinions." It is a tenet deeply-held by copywriters and anchormen alike.
Lazarsfeld and Katz showed that this
"Magic Bullet Theory"
was inaccurate. An earlier Lazarsfeld study had shown that only some 5
percent of Presidential voters had their opinions shaped directly by
media messages. Together, the two scholars showed that media work more
indirectly, through social influence. They identified a "two-step
flow," by which media messages reinforced what people heard from others
in one or another of their communities. These social influencers are,
in the Lazarsfeld and Katz formulation,
"opinion leaders."Many
of the assumptions that still drive modern marketing mavens were
overturned 50 years ago by the two professors. Receiving a message does
not imply responding to it, they showed. Moreover, top-down influence
generally is fairly benign. People belong to numerous communities, and
are influenced in different things by different opinion leaders. But
just try telling that to a high-priced creative with a killer reel. It
seems the world rediscovers personal influence every few years or so --
in the form of "word of mouth marketing," "brand advocacy," "guerrilla
marketing," and "brand zealotry" -- only to forget it the next time a
fabulous, award-winning ad campaign or a depressing, mud-slinging
political campaign comes slamming down the airwaves.

The Facebook notion of defining the world's
"social graph"
-- "the network of connections and relationships between people on the
service," in Facebook founder Mark Zuckerberg's phrase -- and deploying
it in the service of marketers is the latest marketing spin around the
half-century-old work of Lazarsfeld and Katz. (That's Katz at left.)
What's changed, of course, is that when Lazarsfeld and Katz were
writing, the only scalable communications tools available were mass
media, notably the new phenomenon of television. Today, social
networking sites of enormous reach -- larger than television's, because
they have instantaneous global scope -- allow opinion leaders to shape
attitudes in communities far and wide... and near and narrow. That's
the promise underlying Facebook's notion to
"marry an ad message to a user-initiated endorsement of a product or service," as Ad Age put it.
But
Lazarsfeld and Katz bear re-reading, and not just for Silicon Alley
cocktail party one-upsmanship. The importance of personal mediation
means that television, radio, and print communications have always been
filtered in ways their creators could not necessarily predict. The old
saw that "nothing will kill a bad product faster than a great ad" is an
example of this, although few practitioners recognize it. Today, with
the Internet allowing all manner of influencers to wield their opinions
in any way they choose, the relationship between the constructed
campaign and its eventual effects is even more unpredictable.
In
fact, it will take a supremely clever ad agencies and consumer
marketers with strong stomachs to test themselves against the
backlashes that seem all but inevitable. For if there's anything that
might unravel your personal social graph, it'll be too many personal
ads and endorsements tearing through it. The results might look like a
book written by Dale Carnegie's evil twin:
How to Lose Friends and Not Influence People.
