All right. Thank you, Doug, and good afternoon, everyone. I'm pleased to report on our results and the progress we are making on our strategic priorities as we move towards the end of the year. TDS Telecom grew its footprint 6% from a year ago, now serving 1.4 million service addresses across its markets. Based on the successes we have experienced to date, we are increasing our fiber deployment program substantially with the announcement of additional new communities in Wisconsin, Idaho and North Carolina. And we are entering into the state of Montana. This significantly advances our goal to bring state-of-the-art broadband capability and competition to more growing communities.
In addition, we are now capable of delivering 2 gig internet speeds in our Spokane, Washington and Meridian, Idaho markets. And going forward, we'll launch 2 gig products in all of our new fiber expansion markets. Two gigs provides an exceptional customer experience, doubling our previous maximum speed offering and helping to further differentiate us from the cable competition. Also in the quarter, we completed fiber-to-the-home construction in our Southern Wisconsin cluster, where we are seeing total broadband penetration of 38% in this fully-launched cluster. In total, during the quarter, we added 20,000 fiber service addresses, surpassing 40% of our wireline service addresses, a key milestone for us. From a financial perspective, overall, we grew our top line 2%, while planned investment spending on new market launches resulted in lower adjusted EBITDA as expected.
Turning to Slide 18. We remain committed to the strategic priorities we set out at the beginning of the year. As previously discussed, our primary objective is to generate growth by investing in our high speed broadband services. We have a multifaceted approach to this growth that includes leveraging existing networks and constructing greenfield fiber in new markets to expand our footprint. We are very pleased that where we have invested in fiber in our incumbent markets, we have achieved superior market share. And in our expansion markets, we are seeing strong customer preregistrations.
In addition, we continue to drive faster speeds in our more rural incumbent markets by building to meet our A-CAM obligations and utilizing safe broadband grants. We were recently awarded 2 broadband grants in Wisconsin to expand fiber services to 2 rural communities.
Moving to Slide 19. Total residential connections increased 3% due to broadband growth in new and existing markets, partially offset by a decrease in voice connections. Total telecom broadband residential connections grew 7% in the quarter as we continue to fortify our network with fiber and expand into new markets. We are on track in our network construction under the A-CAM program, also helping to drive growth in our incumbent markets. Overall, higher value product mix and price increases drove a 4% increase in average residential revenue per connection.
On Slide 20, you can see the broadband connection growth across all markets. Our focus on fast, reliable service has generated a 13% increase in total residential broadband revenue. We are offering 1 gig broadband speeds to 57% of our total footprint, including both our fiber and DOCSIS 3.1 markets. The 1 gig product, along with our 2 gig product in certain expansion markets, are important tools that will allow us to defend and to win new customers. In areas where we offer 1 gig service, we are now seeing 20% of our new customers taking this superior product.
Turning to Slide 21. We have augmented our success growing broadband with our TDS TV offering. A majority of TDS Telecom's residential customers take advantage of bundling options, as 63% of customers subscribe to more than one service, which helps to keep our churn low. Residential video connections were nearly flat. Wireline growth of 6%, driven by our expansion markets, nearly offset losses in the cable market. Video continues to remain important to our customers. For example, we are experiencing a 38% video attachment rate to every broadband connection in our wireline markets where we offer IPTV services. Our strategy is to increase video connections through the offering of our cloud-based TDS TV+ product. The rollout of this product currently covers 61% of our total operations, including cable.
Moving to Slide 22. We continue to be very bullish on our fiber strategy and how it will transform TDS Telecom in a very meaningful way over the next several years. As we discussed last quarter, given the attractiveness of this opportunity and the heightened level of participation by other overbuilders, our sense of urgency has increased. We have upsized the number of expansion markets we expect to build over the next several years as well as increasing our fiber builds within our existing footprint. Fiber is the most economical long-term solution to deliver the best broadband experience. We continue to refine our market selection criteria and are highly confident in this process.
So now let's turn to Slide 23, which shows the progress we are making this year on our multiyear fiber program, which includes fiber into incumbent markets and also expansion into new markets. As a result of this strategy, 40% of our wireline service addresses are now served by fiber, which is up from 34% a year ago. This is driving revenue growth while also expanding the total wireline footprint 8% to 891,000 service addresses.
On Slide 24, we highlighted the total service addresses for the cluster, the clusters that are in construction and we are actively marketing. We recently announced our expansion of fiber into several new communities. Further expanding our existing clusters, we announced Nampa, Idaho and several communities in Wisconsin, including anchor markets Green Bay and Oshkosh. In addition, we announced several communities that will plant the flag in new geographies: Eau Claire, Sparta and Onalaska, Wisconsin, creating a Western cluster; Billings, Montana, the first in this state; and several communities just southeast of Charlotte in North Carolina, where we operate a cable market today. In total, these communities add more than 270,000 additional service addresses to our existing fiber deployment plan.
Through the third quarter, we have 358,000 total fiber service addresses and are working to build out the footprint in these announced markets, growing to 929,000 service addresses over the next several years. Year-to-date, we completed construction of 51,000 fiber addresses, adding 20,000 service addresses in the quarter. This progress continues to be slower than planned due to permitting complexity and contractor scheduling delays and is putting pressure on service address delivery targets in the fourth quarter. For example, in Meridian, Idaho, we experienced a temporary delay on more than 35,000 service addresses and just recently have restarted construction.
As a result, we expect to fall short of our construction goals this year but still improve our delivery compared to last year. Therefore, we have lowered our guidance for capital expenditures to reflect these delays, but we still expect to be within the guidance range for revenue and adjusted EBITDA for the year. We also continue to proactively manage future construction and customer equipment inventory demand where we are seeing lengthening lead times with our suppliers. As an example, some contractors have experienced staffing shortages and are unable to complete fiber builds in the desired time frame. We will continue to monitor these challenges and update you on our progress going forward.
On Slide 25, total revenues increased 2% year-over-year to $252 million, driven by the strong growth in residential revenues, which increased 6% in total. The chart includes residential revenue mix, which highlights the increasing contribution of our expansion markets. Incumbent wireline markets also showed solid residential growth of 3% due to increases in broadband connections as well as increases from within the broadband product mix, partially offset by a 4% decrease in residential voice connections.
Cable residential revenues grew 6%, also due to increases in broadband connections as well as the product mix. Commercial revenues decreased 6% in the quarter, primarily driven by lower CLEC connections, partially offset by a 5% increase in broadband connections. Wholesale revenue decreased 5% due to certain state USF support timing.
So let me sum up the combined financial results for the quarter as shown on Slide 26. Total revenues increased 2% from the prior year as growth from our fiber expansions and increases in broadband subscribers exceeded the declines we experienced in our legacy business. Cash expenses increased 3% due to both supporting our current growth as well as spending related to future expansion into new markets, which is not yet reflected in our revenues. Future market costs include direct costs such as sales, marketing, real estate and technicians, in addition to shared service costs necessary to support new market growth.
As a result, adjusted EBITDA decreased 2% to $77 million, as expected. Capital expenditures were down 1% to $91 million as increased investment in fiber deployments were offset by decreased spend on core operations.
And on Slide 27, we provided our updated 2021 guidance. Our revenue and adjusted EBITDA are right in line with our expectations. And now that we are closer to the end of the year, we are narrowing our ranges and slightly increasing the midpoint on revenue. We expect revenues to be between $990 million and $1.02 billion, and adjusted EBITDA to be between $295 million and $315 million. With the construction delays and build challenges I mentioned earlier, we are lowering our expectations for capital expenditures to be between $400 million and $450 million.
It's the dedication and hard work of all our associates that contribute to our company's success. And for that, I am grateful. I look forward to sharing our final 2021 quarterly results with everyone in February.
Now I'll turn the call over to Jane.
