News Release Details

SEATTLE, WA - August 9, 2007

Marchex, Inc. (NASDAQ: MCHX, MCHXP), a local online advertising company and leading publisher of local content, today announced that it has named Internet veteran Bill Day as Chief Media Officer. In this newly created role, Day will oversee Marchex's media strategy, including its online content, consumer-facing initiatives and related advertising strategies.

With this announcement, Day assumes responsibility for certain areas and strategies which previously were directed by Marchex Chairman and Chief Executive Officer Russell C. Horowitz. Day, who assumes his new position immediately, will report directly to Horowitz.

"Local search and locally developed and oriented content will be one of the key drivers for the search market over the next five years and Marchex is in a phenomenal position to be a leader in this category," said Day. "I believe that Marchex's innovative content initiatives are truly ahead of the curve and I look forward to building on the current momentum and helping to take Marchex's local consumer experience and related advertising opportunities to the next level."

"Bill's extensive track record and expertise in building innovative, consumer media properties and in operating online advertising businesses will enable him to provide important strategic direction to our consumer-facing initiatives," said Horowitz. "With Bill's leadership, we are well positioned to realize the significant growth potential of our network and develop it into a leading brand in the local space."

Prior to joining Marchex, Day was a co-founder and CEO of About.com, a pioneer in providing vertically focused original consumer information and advice. He grew About.com to one of the most highly trafficked content destinations on the Internet, a top 20 global online media network covering more than 700 topics and 50,000 subjects used by tens of millions of monthly users to find highly targeted, useful information. While at About.com, he also pioneered contextual pay-per-click advertising through the launch of the Sprinks Network. Following Primedia's acquisition of About.com in 2000, Day continued as CEO of About.com, running the division within Primedia through 2003. More recently, from 2004 to 2007, he has been the CEO of MeMedia (formerly WhenU), a privately-held behavioral advertising network. He received his B.S. in Mechanical Engineering from Yale University, and his M.B.A. from the Wharton School of the University of Pennsylvania.
