Comcast will be buying a financially strapped municipal cable operation run by Alameda Power & Telecom in the San Francisco Bay Area. According to Multichannel News, Comcast will pay $15 million for the system, which has 9,500 video customers and 6,600 data customers just outside of San Francisco. The municipal utility started as an electrical company, then got into video and broadband services in 2001. The outfit funded their plan with revenue bond anticipation notes, and now faces a balloon payment of $35 million on those notes in June.
