RCN Recognized as "Who's Who" Business Leader in Lehigh Valley, PA for Fourth Consecutive Year

Residents of Lehigh Valley recognize RCN as a business leader.

Herndon, VA (Vocus) February 21, 2007 -- RCN Corporation (NASDAQ: RCNI), a leading triple play provider of competitive cable television (http://www.rcn.com), high speed internet (http://www.rcn.com) and local and long distance telephone services, announced today that it has received 2007 "Who's Who in Business" recognition by the residents of the Lehigh Valley, Pennsylvania area for the fourth consecutive year.

"We're extremely pleased to be starting off 2007 with the vote of confidence that the citizens of Lehigh Valley have given us by this recognition," said John Filipowicz, RCN's president of residential markets.

The annual distinction of being identified as a prestigious member of "Who's Who in Business" is determined by Lehigh Valley residents. An independent market research firm conducted surveys within a geographically dispersed, random sample of households and from those results identified leaders in 75 different business categories. RCN was named "Who's Who" as a leading television/cable provider for 2007 and has received this recognition every year since 2004.

"Our employees have been working hard to provide the best service and customer support and this positive acknowledgement energizes our commitment to our communities and customers that we serve today and plan to serve in the future," explained Filipowicz.

Members of RCN Pennsylvania's management team will be honored at the Annual Who's Who Luncheon and Awards Presentation on March 1, 2007, which is sponsored by Lehigh Valley Style.
