Neilsen,
TiVo Try Ratings Game
By Steve Friess
In an effort to devise new ways to gauge
yet another new, hard-to-measure television audience, Neilsen
Media Research launched an experiment this summer to collect
viewership data on the TiVo personal recorder from 20 homes
scattered across the United States.
Neilsen technicians spent much of the summer
wiring up their meters to the TiVo units, all of which carry
new software from TiVo that enables Neilsen to track what
is recorded as well as if and when the recordings are viewed.
The 20 homes include 10 that were already
Neilsen households for national ratings. All received a free
TiVo unit as part of their agreement to participate.
"TiVo and other time-shifting devices have
all the earmarks of being a real consumer hit," Neilsen spokesman
Jack Loftus said. "Time-shifting will be something more people
are really comfortable with. We never know if the technology
is going to sizzle or fizzle, but you can't wait until it
takes off before you say, 'Hey, maybe we should measure this.'"
TiVo allows viewers to download shows onto
a hard drive for later viewing as well as to "pause" the TV
and then pick up where they left off, regardless of the elapsed
time. So far, Loftus says, the device that debuted in 1998
is only in about one-half percent of U.S. households.
The experiment comes as Neilsen, which focuses
mainly on TV viewership, is also joining radio-ratings king
Arbitron in another field test that could hold the key to
measuring Internet radio and TV, another new ratings riddle
for researchers to decipher.
In that effort, now in its second year, 1,500
people in the Philadelphia area are carrying Portable People
Meters that hear inaudible codes from the TV and radio.
The message is picked up by the pager-sized
gizmo carried by participants who place the device into a
base station at the end of the day to transmit the day's data
to Arbitron and recharge the meter. Arbitron, the lead player
in this effort, persuaded 47 radio stations, 11 broadcast
stations and 25 cable networks to encode their programming
for the experiment.
In March, two radio stations, WDEL (1150
AM) and WSTW (93.7 FM) put on separate codes for their broadcast
and their Internet streams to test whether the PPMs could
tabulate that information separately.
Next up is creating a second 1,500-participant
group in Philadelphia to prove the data is accurate by showing
that it is similar in both samples.
Arbitron spokesman Thom Mocarsky said the
PPM could resolve the biggest challenge in the constantly
shifting world of ratings collection: that people are using
media in more different places all the time.
Particularly in radio, listenership figures
are always suspect.
"This is an entirely new and different way
to measure TV and radio, because this measures the person,
not the appliance," Mocarsky said.
"Instead of wiring boxes to TV sets, which
is expensive and requires a lot of labor, we're giving meters
to people. Every time a person is in the presence of a coded
media, the PPM knows."
The PPM also knows whether a participant
forgets to carry it because it contains a motion sensor. That
helps' counter the age-old problem of survey participants
whose data has large gaps because, for instance, they don't
fill out their ratings diary fast enough to remember all of
what they listened to and when.
"We find on average 80 percent of the time
the PPM gets carried," Mocarsky said. "That's not bad. We
want to improve that 80 percent, so we have to learn how to
make it so the people don't forget or remind them in such
a way that we don't annoy the hell out of them."
Currently, Arbitron radio ratings rely solely
on the 1.5 million people who each take one-week stints at
manually filling out diaries throughout the year. Neilsen's
local and national overnight ratings rely on households connected
to ratings meters, and Neilsen also sends out about 1 million
diaries as well for supplemental viewership data.
If the PPMs are proved successful -- and
Mocarsky declined to offer a time frame for determining that
-- then Neilsen would use it for TV ratings and Arbitron for
radio ratings. The convenience of the devices would help the
companies attract more participants and vastly expand the
sample size, a much desired result in a world with an ever-expanding
number of TV and radio stations.
Yet PPMs wouldn't solve every problem, so
Neilsen will launch yet another experiment this fall to measure
audiences involved with "interactive television." Loftus declined
to detail what this effort would entail, but said the point
is to show advertisers the effectiveness of tie-ins between
TV and the Internet.
"If I'm watching Friends and at the same
time clicking onto a website for something I've seen on Friends,
how do we measure that?" Loftus said. "I want to know if the
viewer saw something on TV and, as a result, accessed my website."
