Revenues increased 4.3% and 3.6% for the three and nine months ended September 30, 2018, respectively, primarily due to greater HSD and, to a lesser extent, business services, phone and, for the three months ended September 30, 2018, advertising revenues, offset in part by lower video revenues. Revenues were unfavorably impacted and substantially unaffected for the three and nine months ended September 30, 2018, respectively, by the timing change to revenue recognition as noted in “Revenues –Changes in Accounting Standards,” and, excluding the impact of such change, revenues would have increased 4.5% and 3.6% for the three and nine months ended September 30, 2018.
We lost 1,000 and gained 1,000 customer relationships during the three and nine months ended September 30, 2018, respectively, compared to no net change in customer relationships for the three and nine months ended September 30, 2017, respectively. Average total monthly revenue per customer relationship was $121.97 and $120.72 for the three and nine months ended September 30, 2018, respectively, representing increases of 3.9% and 3.4% over the respective prior year periods.
Video
Video revenues declined 4.7% and 3.7% for the three and nine months ended September 30, 2018, respectively, mainly due to the timing and allocation changes to revenue recognition noted in “Revenues– Changes in Accounting Standards,” and, to a lesser extent, smaller residential video customer bases compared to the prior year periods, offset in part by rate adjustments associated with the pass-through of higher programming costs for retransmission consent fees, and more customers taking our advanced video services. Excluding the impact of the timing and allocation changes, video revenues would have decreased 1.6% and 1.4% for the three and nine months ended September 30, 2018, respectively. We lost 10,000 and 18,000 video customers during the three and nine months ended September 30, 2018, respectively, compared to losses of 4,000 and 8,000 video customers during the respective prior year periods. As of September 30, 2018, we served 437,000 video customers, or 28.8% of estimated homes passed, and 42.4% of our residential video customers took our DVR service, which represents the largest component of advanced video services revenues.
HSD
HSD revenues grew 11.8% and 10.1% for the three and nine months ended September 30, 2018, respectively, mainly as a result of more customers paying higher rates for faster speed tiers, larger residential HSD customer bases compared to the prior year periods, and the timing and allocation changes to revenue recognition. Excluding the impact of the timing and allocation changes, HSD revenues would have grown 9.6% and 7.9% for the three and nine months ended September 30, 2018, respectively. We gained 4,000 and 26,000 HSD customers during the three and nine months ended September 30, 2018, respectively, compared to increases of 4,000 and 16,000 HSD customers during the respective prior year periods. As of September 30, 2018, we served 694,000 HSD customers, or 45.8% of estimated homes passed and 72.6% of our residential HSD customers took our wireless home gateway service.
Phone
Phone revenues increased 3.3% and 3.6% for the three and nine months ended September 30, 2018, respectively, primarily due to the timing and allocation changes to revenue recognition and larger residential phone customer bases compared to the prior year periods, offset in part by greater levels of discounting within the bundled packaging of our services. Excluding the impact of the timing and allocation changes, phone revenues would have decreased 2.9% and increased 0.5% for the three and nine months ended September 30, 2018, respectively. We gained 4,000 and 24,000 phone customers during the three and nine months ended September 30, 2018, respectively, compared to increases of 12,000 and 36,000 phone customers during the respective prior year periods. As of September 30, 2018, we served 336,000 phone customers, or 22.2% of estimated homes passed.
Business Services
Business services revenues grew 9.0% and 9.4% for the three and nine months ended September 30, 2018, respectively, principally due to larger SMB customer bases compared to the prior year periods and, to a much lesser extent for the nine months ended September 30, 2018, the timing change to revenue recognition. Excluding the impact of the timing change, business services revenues would have grown 8.8% and 9.2% for the three and nine months ended September 30, 2018, respectively.
