Advertising revenue for the three main television networks in the US has fallen compared with the same period last year.

A report by the Broadcast Cable Financial Management Association says ABC, CBS and NBC saw a 2% revenue drop in the second quarter and in the first half of 2005.

Combined ad revenue for the trio was $2.85 billion (€2.31bn; £1.57bn) for Q2, down year on year by approximately $52 million. In the first half of 2005, network revenue totalled $5.73bn, $113m less than the first half last year.

But, says the BCFMA, the 2004 figures reflect an atypically good year which included the Athens Olympic Games and the presidential election.

When compared with with 2003, the numbers reveal a first half increase of around 7%, or more than $152m. Association president Mary Collins says the networks are "on track with industry estimates".
