InterMute's Flagship Product Beats All Other Ad Blockers in Units Sold at Retail

BRAINTREE, Mass. - Dec. 8, 2003 - InterMute, Inc. today announced that its flagship product, AdSubtract, was the top selling ad-blocking software and the third best selling business software overall in units sold at retail in September.

According to the NPD Group, a company that tracks and reports retail software sales, the only business software titles that sold more than AdSubtract in September were Microsoft Office XP (academic edition) and QuickBooks 2003 PRO. The data was compiled from over 70 NPD channel partners, representing 90% of the USA consumer retail market. Many of the world's most successful companies rely on NPD for critical knowledge on what is selling, where and why.

InterMute's AdSubtract product allows Internet users to block unwanted web advertising, so web ads no longer clutter their screens and slow their web surfing. Since 1999, AdSubtract users have blocked billions of unwanted Internet ads, including Pop-ups and banner ads.

"We are happy, but not surprised, that AdSubtract has done so well at the retail level," said Ed English, CEO, InterMute. "Internet users feel under attack from the barrage of Internet ads. Smart consumers know InterMute provides the simplest and most effective solution for filtering unwanted Web clutter. Our retail sell-through sales figures show the market recognizes InterMute is the industry leader and relies on AdSubtract as the best solution available."

InterMute delivers the most powerful and innovative filtering software for blocking Internet ads, Spyware, Spam and other annoying Web distractions.

In related news today, InterMute unveiled the latest version of AdSubtract - AdSubtract PRO 3. A new feature called "Search Sanity" enables users to block paid or sponsored Search Engine results, addressing the fastest growing segment in the online advertising industry.
