In-Car Cell Phone Use Impacting Radio Listening!

Bridge Ratings recently completed its first six month analysis of in-car cell phone use and its potential impact on other in-car listening including that of radio. The study was commissioned by a wireless company in 2005 as part of a multi-year consumer study.

Cell phone pervasiveness is a significant contributor to threat to traditional media by cell phone use in vehicles. Topline findings of our national study conducted between July 2005 and January 2006 estimates that in the United States, 70.3% of the population owned a cell phone in 2005. At the time of the study, U.S. population was estimated at at 297 million, with 209 million cell phone users. In fact, today cell phone technology is the only audio technology that could approach traditional radio's market penetration (currently at 93% or 276 million Americans who listen to terrestrial radio at least once a week).

During the time when cell phone calls were made or received, attention was placed exclusively on the phone call and not on the radio.

The following charts represent cell phone use and behavior.
