Despite competitive pressures from telcos and direct broadcast satellite providers, cable's triple-play (video, data and voice) revenue streams are still expanding due to growing penetration of their subscriber bases, according to SNL Kagan's "Broadband Cable Financial Databook" study, reports MarketingCharts.

Other cable revenue sources - such as commercial services and advertising - will help maintain future growth, SNL Kagan said.

According to the Databook' forecasts…

• With advanced services capturing a growing proportion of subscribers and basic subscriber churn slowing thanks to the stickiness of the new services, cable revenue generating units are projected to increase to 200 million in 2012, from 152 million at yearend 2007.
• Cable multiple system operator revenues are projected to grow to $115.4 billion in 2012 from $79.1 billion in 2007, with the average revenue per subscriber increasing to $140.08.

Among other highlights from the Broadband Cable Financial Databook:

• Cable RGUs (revenue-generating units) increased to 137.6 million in 2006 from 125.1 million at yearend 2005 and are on track to grow to 151.6 million by yearend 2007.
• Cable VoIP homes marketed will leap to an estimated 95.5 million by yearend 2007 from 31.0 million at yearend 2005.
