Our other operations in western Europe 11 added 373,000 RGUs collectively in 2012, reflecting year-over-year growth of 5%. This growth was derived from improved subscriber performances in Switzerland, Austria and Belgium, offset by a year-over-year decline in our Dutch business, which faced a more competitive environment during the second half of 2012. Rounding out our European footprint, our Central and Eastern European (“CEE”) region added 329,000 RGUs in 2012, our highest annual total since 2007 in that region. Additionally, our Chilean and Puerto Rican operations contributed 105,000 and 20,000, respectively.
In terms of our TV business, we lost 287,000 video subscribers (including just 28,000 in Q4) in 2012, which reflected a 7% improvement compared to our video losses in 2011 and represents our lowest annual video attrition in five years in absolute terms despite a significantly larger footprint. We finished 2012 with a digital video base of 9.1 million RGUs, as we added 920,000 digital cable RGUs (including 217,000 in Q4) during the year. As a result, our digital penetration 12 increased to 52% compared to 46% at year-end 2011. We expect that our opportunity to continue driving digital upgrades will be enhanced by our recently launched Horizon TV product and with nearly 8.5 million analog video subscribers, we remain confident in the video growth opportunity. The take-up of Horizon TV in the Dutch market remained robust during the fourth quarter, and the early results so far in Switzerland have been very positive. We look forward to launching Horizon TV in Germany and Ireland later this year.
Overall subscriber growth was powered by our market-leading double- and triple-play bundles, with our superior broadband internet products serving as the key competitive differentiator. As a result of the strong demand from within our customer base, we added over 900,000 broadband internet subscribers (including 249,000 in Q4) and over 970,000 telephony subscribers (including 244,000 in Q4) reflecting year-over-year growth of 19% and 32%, respectively, both of which represent record annual additions.
