According to an NAA estimate released Friday, print-ad revenue plunged 9.4 percent to US$42 billion in 2007, the Wall Street Journal reported.

Although newspapers’ online ad revenue is expanding, the extra money being made off the Internet will not help in balancing the lost print revenue. Newspapers experienced an ad spending decline of 7.9 percent in 2007, including the online revenue.

Last week, TNS Media Intelligence reported that its panel of 144 daily papers, 52 Spanish-language papers and 3 national papers witnessed ad revenue decreases of 5.6 percent in 2007, according to the Wall Street Journal.

“We have no evidence to show that the bottom has been reached yet,” Gordon Borrell, chief executive of media research firm Borrell Associates, told the Wall Street Journal.
