For the three months ended September 30, 2012, we lost 90,000 video RGUs, which was largely consistent with the losses we experienced during each of the first and second quarters of 2012 and compares to video losses of 59,000 for Q3 2011. The quarterly year-over-year increase was related in part to our German video losses of 26,000 in Q3 2012 as compared to video losses of 7,000 in Q3 2011. These losses stemmed from a combination of a video price increase for certain single dwelling units and the loss of a housing association contract during the quarter. Additionally, we were also impacted by heightened competitive environments in Poland and Chile, as our Polish and Chilean net video losses increased by 18,000 and 11,000, respectively, on a year-over-year basis.
In terms of digital cable additions, we added 180,000 and 703,000 for the three- and nine-month 2012 periods, respectively, led by strong performances in our Belgian, Polish, German and Swiss operations. With this continued success, our digital base increased to 8.8 million RGUs at quarter-end, boosting our digital penetration 8 above 50%. A key development for us in Q3 was the long-awaited launch of Horizon TV in the Netherlands, which will help us differentiate our product offerings not only in the Netherlands in coming quarters, but also in markets like Switzerland, Ireland and our largest market, Germany.
Our bundles continue to emphasize our speed advantage for broadband internet and our attractively-priced telephony services. For the three and nine months ended September 30, 2012, we generated broadband internet RGU additions of 198,000 and 660,000, respectively, which reflect year-over-year growth rates of 3% and 23%, respectively. In addition, we added telephony RGUs of 211,000 and 728,000 during the three- and nine-month 2012 periods, respectively, which represent year-over-year improvements of 9% and 44%.
RevenueFor the three and nine months ended September 30, 2012, our consolidated revenue increased 4% to $2.5 billion and 7% to $7.6 billion, respectively, as compared to the corresponding prior year periods. Both results were positively impacted by acquisitions, principally Kabel BW, and continued subscriber growth, as we added 1.5 million organic RGUs during the last twelve months. On a comparative basis, our revenue growth was adversely impacted by negative foreign currency (“FX”) movements associated with the translation effect from a strengthening U.S. dollar. Adjusting for both the impact of acquisitions and FX, we achieved year-over-year rebased revenue growth of 6% for each of the three- and nine-month 2012 periods.
