	Portable People Meter - Wikipedia, the free encyclopedia
		The Portable People Meter (sometimes mistakenly "Personal People Meter") or PPM, is a device developed by Arbitron (and now jointly with Nielsen) to measure how many people are listening (or at least exposed) to individual radio stations and television stations, including cable TV.
		The PPM is worn like a pager, and detects hidden audio tones within a station or network's audio stream, logging each time it finds such a signal.
		A base station for each PPM, where each person in the household places it overnight to recharge the battery and to transmit information to the hub.

	Portable People Meter
		Portable People Meter, which is worn by a consumer to detect and record the inaudible codes in the programming that the consumer is exposed to;
		The Portable People Meter is also equipped with a motion detector, which is linked to a small green light that is visible to the survey participant.
		As long as the meter is being carried, the motion detector senses the smallest movement and keeps the green light illuminated.

	Expect a delay for Portable People Meter
		The other, more ominous possibility is that the PPM results are indeed reflective of true media use and that the diaries are even less reliable than even their worst critics suspected.
		The rating from the PPM for broadcast and cable TV, in fact, was 81 percent higher than the diary rating for people 6-17 years old.
		PPM participants only have to wear a pager-sized device, which picks up inaudible signals from TV and radio broadcasts, and put it in a docking station at night to download the data to Arbitron.

	Nielsen and Arbitron Continue to Test Portable People Meter (PPM)
		Meter Sensitivity – We need to better understand the potential impact of using an audio-based definition of viewing by evaluating how often unintended viewing is reported by the PPM in various sample environments.
		The industry-agreed standard definition of “television audience” is based on people in the sample reporting when they consider themselves to be “watching or listening” to television.
		The Arbitron PPM reports when a person is in the audience based on detection of embedded codes in the program audio.

	Radio People Meter
		Under the PPM system, station rankings in the Houston metro market remained largely unchanged when compared to diaries, but morning-drive ratings decreased significantly across the market, from a 14.2 rating to 9.2.
		The Houston PPM trial is the second one the company has conducted in the U.S. (the first was in Philadelphia) and was chosen because of its diverse population.
		PPM is a passive measurement system in which participants carry a small pagerlike device that picks up inaudible codes embedded within the audio streams.

	washingtonpost.com: The Portable People Meter Knows All
		For the past few years, about 1,500 people in the Philadelphia area have worn small electronic devices that keep track of every bit of radio programming they might hear in the car, at the office, as they walk to lunch, when they drop by a friend's house or when they hit happy hour after work.
		The number of people who agreed to take $2 a week to complete a diary dropped from 43 percent of those asked in 1995 to 34 percent in 2002.
		The people meter is still a few years from nationwide deployment, but eventually it will track not only radio listening, but every kind of media exposure, from TiVo to Web surfing, cable to satellite.

	SABO MEDIA: Portable People Meter
		The Portable People Meter, worn by daily respondents, picks up that code wherever the participant is exposed to an encoded signal that would be audible to the human ear.
		Every night, participants dock their PPM units in PPM docking station where the media exposure data is uploaded to Arbitron and the PPM unit is recharged for the next day.
		The PPM is resilient; the medium from which it is recording exposure doesn't matter as long as the signal is encoded and the programming is audible to the participant.

	Measurement for the Future
		Since the Portable Meter does not need to be attached to a radio receiver, radio audiences can be measured electronically for the first time since the development of the car and portable radio.
		The components of the Portable People Meter system are so easy to install and the tasks required of the respondent are so simple that the equipment could be shipped to survey households and set up by the householders.
		Because the Portable Meter doesn't require any decision making about whether to press a button or to write down an entry or to remember what was seen or heard, all exposures to encoded content are recorded completely and objectively.

	Measuring the media
		The PPM is in the last stages of several years of field-testing, first in England and now in Philadelphia.
		At the end of every day, the PPM holder puts his meter into a base station cradle at home that will recharge the batteries and send the data from the collected codes to Arbitron to be tallied.
		PPM participants will be given higher incentives and rewards to wear or carry the device every day, all day except overnight when the PPM is set in its cradle.

	Questions over Portable People Meter
		A major concern revolves around data that show people listen to twice as many radio stations as previously thought and that stations, on average, have 10 times the number of least-frequent listeners with the PPM as they did with the diary.
		Arbitron says the PPM is picking up people who do not fully report listening with the diary, but some media people think the system, which picks up inaudible codes embedded in radio, television and cable signals, is simply picking up too many people.
		A second panel of 1,000 people will be added in Philadelphia, which will be used as a control study to ensure that the PPM results are not a fluke but the product of a valid system, with acceptable response rates and a sample reflective of the population.

		The initial results coming out of the Arbitron Portable People Meter (PPM) tests suggest the current approach and thinking we apply to programming our radio stations in the future may have to undergo a thorough review.
		Advantages of PPM measurement include what should be much more accurate data; eliminating diarykeeper rounding and errors alone, which will give them a more realistic listening picture. While we see higher cume, TSL will likely dip, but only slightly. Indeed, in the early day of its release, this is actually what happened.
		PPM data showed nearly twice the number of stations listened to daily, but on an average of 18 minutes less per day of TSL. These numbers are compared to the diary retrieval system that is now utilized by Arbitron.

		These early meters were neither portable nor people-friendly, being the size of a brick and nearly 20 times heavier than the present model.
		At bedtime, the PPM is "docked" in its Base Station, which downloads the meter's records of what it heard that day and how much it was worn, and recharges its battery.
		The agree rate for the PPM field test in Manchester in 1999 was 39 percent, which "compares quite well to the generally lower agree rates presently achieved by TV meter panels in the United States and Europe, even those using in-person recruitment methods," according to the report.

		Mocarsky, vice-president of communications with Columbia, Md.-based media research firm Arbitron, says his company's Portable People Meter will be able to gauge what people are watching and listening to even when they're not at home.
		The PPM is a small, pager-sized device that relies on audio encoding of broadcast signals to track an individual's consumption of television, radio or Internet programming.
		The concept was first introduced to the Canadian marketing industry in 1992, but at the time, the PPM was thought to be too unwieldy and its battery life too short for practical consideration.

		The ACA (Association of Canadian Advertisers) has warned its members that it is very concerned about the decision by the TV viewing research (BBM Canada) to deploy the new portable people meter system.
		MacKenzie is a vociferous advocate of PPMs, not least because the system shows his minority TalkSport radio station in a more favorable light than the official RAJAR data.
		The case is due for a court hearing in November, although few observers of the UK media scene believe it will see light of day, dismissing the lawsuit as a mere negotiating ploy.

		In the radio and television industry, this little box is known as the portable people meter, or the P.P.M. In both a business and a cultural sense, it also seems to be the equivalent of a large explosive.
		The technology underlying the PPM (currently trialing in Houston) is interesting: they bury a unique, repeating, inaudible digital code in the audio tracks of TV and radio shows.
		The PPM can do things like register the impressions on ads that screen at movie theaters; with a GPS-additive it could track whether you walked past a particular billboard; with RFID capability built in, it could tell that you happened to pick up a copy of the New Yorker, etc. etc.

		It turns out that the more accurate meters showed it was losing viewers to cable, a trend that will soon become clear for all to see in stunningly intimate detail.
		The people at Arbitron wondered if maybe it would be better to measure the person, as opposed to the appliance.
		If advertisers are becoming increasingly unhappy with their ability to get accurate readings in a world where technology is becoming more portable, well, this portable people meter follows that trend in a lot of ways.
