FOR IMMEDIATE RELEASE

ARBITRON INC. REPORTS 2003 FIRST QUARTER FINANCIAL RESULTS
First quarter revenue up 8.3%; Net income up 13.2% over 2002
Net income per share increases 10.4%

NEW YORK, April 17, 2003 – Arbitron Inc. (NYSE: ARB) today announced results for the quarter ended March 31, 2003.

For the first quarter 2003, the Company reported revenue of $71.4 million, an increase of 8.3% over revenue of $65.9 million during the first quarter of 2002. Earnings before interest and taxes (EBIT) for the quarter were $29.9 million, compared with EBIT of $27.6 million during the comparable period last year. Net income for the quarter was $16.1 million, compared with $14.2 million for the first quarter of 2002.

Cost and expenses for the first quarter increased by 8.6%, from $37.1 million in 2002 to $40.2 million in 2003. Interest expense for the quarter declined 21.2%, from $4.6 million in 2002 to $3.6 million in 2003, due to reductions in debt between the two periods.

Net income per share for the first quarter 2003 increased to $0.53 (diluted), compared with $0.48 (diluted) during the comparable period last year.

Commenting on the results for the first quarter, Stephen Morris, president and chief executive officer of Arbitron, said, “In the first quarter of 2003, we met our financial goals for revenue and profitability, a gratifying performance during a period in which global events brought a great deal of last minute uncertainty to the media industry.”

“We have worked hard to keep our core services–ratings, Scarborough and software–as valuable, revenue-generating resources for our broadcaster, cable, agency and advertiser customers. In the first quarter, we increased our efforts to train those who work on the buy and sell sides of the media industry. Our continuing goal is to help our subscribers get the maximum value from the dollars they invest in our services,” said Mr. Morris.

“We also strengthened our relationship with Nielsen Media Research, Inc., our potential joint venture partner for commercial deployment of the Portable People Meter (PPM) in the United States,” continued Mr. Morris. “Last month, Arbitron and Nielsen announced an expansion of our agreement that increases the financial involvement and commitment of resources from Nielsen in a joint research program for the PPM. Already, we are in the field with studies that are designed to further develop the PPM system as a local market ratings service. Even as we work with Nielsen, we are also developing a number of other applications for the Portable People Meter technology that we could implement on our own.”

“In international markets, we continue to make progress marketing the PPM. While the Australian radio industry has deferred a decision regarding electronic measurement, IBOPE, the leading South American media research firm, has just concluded a successful evaluation of the PPM encoding technology in Brazil. Médiamétrie, the leading media research firm in France, has just signed an agreement for a two-year evaluation of the PPM in Paris,” Mr. Morris concluded.

Arbitron will host a conference call at 10:00 a.m. ET on April 17th to discuss its first quarter results and other relevant matters. To listen to the call, dial the following telephone number: 1-888-262-9189. The call will also be available live on the Internet at the following sites: www.arbitron.com, www.ccbn.com and www.streetevents.com

Note: The Company has reclassified certain data in the 2002 Consolidated Statement of Income to conform with the 2003 presentation.
(1)  EBITDA is presented as supplemental information that management of Arbitron believes may be useful to some investors in evaluating Arbitron because it is widely used as a measure of evaluating a company’s operating performance, as well as to evaluate its operating cash flow. EBITDA is calculated by adding back net interest expense, income tax expense, depreciation and amortization to net income. EBITDA should not be considered a substitute either for net income, as an indicator of Arbitron’s operating performance, or for cash flow, as a measure of Arbitron’s liquidity. In addition, because EBITDA is not calculated identically by all companies, the presentation here may not be comparable to other similarly titled measures of other companies. A reconciliation from EBITDA to cash flow from operations follows:

(2)  Prior to the spin-off from Ceridian Corporation, Arbitron distributed its earnings to Ceridian. Those distributions, together with a $250 million distribution made to Ceridian on the date of the spin-off, gave rise to the stockholders’ deficit. Proceeds from the issuance of long-term debt were used by Arbitron to make the $250 million distribution.
