MOBILE AUDIO IS A SIGNIFICANT GROWTH OPPORTUNITY SAYS ARBITRON/TELEPHIA STUDY

Current Mobile Audio Users Spend More Time than the General Wireless Population on Nearly Every Media and Entertainment Activity

NEW YORK and SAN FRANCISCO--April 3, 2007-- Mobile audio is a promising opportunity that has not yet been fully exploited. That is the conclusion of a landmark study by Arbitron and Telephia that examines the evolving market for mobile audio services from the consumer point of view in terms of current usage patterns, attitudes and preferences.

Key findings from the study include:

•  One in 16 mobile phone subscribers (6 percent) report using one or more mobile audio features in the last 30 days.

•  Downloading music over-the-air has the highest awareness among the general mobile population. Listening to music transferred from another device is the most commonly used way of accessing mobile audio.

•  Current mobile audio users spend more time than the general mobile population on nearly every media and entertainment activity. The exception: current mobile audio users report spending significantly less time per day watching TV (2 hours 33 minutes) than do typical wireless subscribers (3 hours 17 minutes).

•  Mobile audio users represent a lucrative segment of the wireless marketplace. A larger percentage of mobile audio users (56 percent) spend more than sixty dollars a month on wireless subscriptions than the general mobile phone user population (49 percent).

•  Most current mobile audio users agree that commercials are a fair price to pay for free content. More than three quarters of those who download content over-the-air and those who listen to free FM radio agree that commercials are a fair price to pay for free content. Two out of three subscription radio users also agree that commercials are a fair price to pay for free programming.

•  Nearly two-thirds (63 percent) of current mobile audio users are male. People aged 25 to 44 represent 71 percent of all current mobile audio users. African-Americans, Asians and Hispanics make up a higher proportion of current mobile audio users than they do of the general mobile phone user population.

•  Pop music is the leading music style for mobile audio users. The format preferences of current mobile audio users are broadly consistent with the group's demographic profile.

•  Attracting new consumers to the mobile audio marketplace will be challenging. Approximately two-thirds of “non-current” mobile audio users are "not interested at all" in any of the four major options for accessing mobile audio services.

"There is an opportunity for wireless providers, programmers and marketers to develop an advertising model for mobile audio," said Wayman Leung, senior product manager, Telephia. "Most current mobile audio users prefer the ad-supported model over paying a subscription fee. And this group is a very attractive demographic for advertisers to target as it's comprised mainly of affluent, tech-savvy early adopters."

"For broadcasters looking to expand their platforms beyond terrestrial radio, mobile audio represents an untapped marketplace that they can exploit in partnership with mobile phone networks," said Neal Bonner, product development manager, Arbitron Inc. "Radio broadcasters are uniquely positioned to deliver programming for these promising new audio services."

This mobile audio study brings together two industry-leading market research companies in their respective fields. Telephia is the world's largest provider of syndicated consumer research to the telecom and mobile media markets. Arbitron Inc. is an international media and marketing research firm best known for measuring network and local market radio audiences in the United States .

How the Study Was Conducted

A 15-minute online survey of over 2,000 wireless subscribers was conducted in February 2007 to investigate Americans' use, preference and perception of different types of mobile audio. The respondents included a group of approximately 1,100 Current Mobile Audio users, 300 Former Mobile Audio users and 600 Non-Mobile Audio users. These target groups were pre-identified in the Q3 2006 to Q1 2007 Telephia Attitude & Behavior Study. The Telephia Attitude & Behavior Study, conducted monthly, is an online survey of over 300,000 adults annually. It provides a nationally representative view of the U.S. mobile subscriber and of the U.S. mobile market.
