HERNDON, VA — RCN Corporation (NASDAQ: RCNI), a leading provider of all-digital and high-definition video, high-speed internet, and premium voice services to residential and small-medium business customers, as well as high-capacity data transport services to carrier and large enterprise customers, today announced its second quarter 2009 results.

Customers, RGUs and Digital Penetration

Compared to the second quarter of 2008, Residential/Small-Medium Business customers increased to approximately 430,000 and total revenue generating units increased to approximately 911,000, as continued growth in video and data RGU’s was partially offset by a reduction in voice RGU’s, consistent with trends for highly-penetrated landline voice providers. Bundle rate decreased slightly to 67%, and digital video penetration rate remained flat at 91% of video customers, with metro markets maintaining 100% digital penetration through the completion of Project Analog Crush.
