Thanks, Doug, and good morning, everyone. We are pleased with our results at TDS Telecom for the first quarter. We are tracking to our financial guidance expectations and had strong growth in our fiber program. As planned, we added 22,000 marketable fiber service addresses to our footprint and continue to execute on our fiber strategy. Since February, we announced our expansion into 4 new markets in Montana and several communities in Wisconsin. We also completed fiber construction in our central Wisconsin cluster and are pleased with our results to date.
We remain committed to the same strategic pillars we have focused on for several years. Our primary strategic objective is to provide growth and improve returns by investing in our flagship product, high-speed broadband. We are directing our investments to expand our fiber footprint in new and existing markets and to enhance our product offerings, and these investments are driving revenue growth.
At the FCC's upcoming meeting in May, an extension of the A-CAM program will be considered, which we aggressively advocated for and fully support. We anticipate an extension program would provide additional years of revenue support in exchange for deploying higher speed -- higher broadband speeds. Extending the current federal A-CAM program, along with the IIJA broadband funding, would provide even more opportunities for TDS Telecom to help bridge the digital divide in our most rural areas.
Turning to Slide 19. We highlight the achievements we've made for this quarter. As mentioned, we announced 4 new fiber markets in Montana, Great Falls, Butte, Missoula and Helena. We also announced 2 new markets in Wisconsin: Janesville and Brookfield, and we expanded our western Wisconsin cluster by 2 additional communities. Beginning in 2022, we are now measuring fiber service addresses in our cable markets as we are deploying fiber in opportunistic areas such as greenfield development. We deployed 22,000 marketable fiber service addresses in the quarter and are working hard to reach our target of 160,000 for the year. Seasonality will impact the quarterly cadence of fiber service address delivery, starting slowly in the first quarter and steadily building throughout the year.
33% of our total footprint is now served by fiber, and this metric, as I mentioned, now includes fiber in our cable markets. As a reminder, as reported in February, we expect to serve approximately 60% of our total footprint with fiber by 2026. As we look to deliver our service address goals for the rest of the year, we continue to manage a variety of industry-wide headwinds, including inflation, supply chain and contractor performance challenges. We are working to mitigate these headwinds and are pleased to have a robust pipeline of markets to help us pivot if necessary.
In line with our growth objectives, service addresses grew 7% year-over-year. In the first quarter, we completed the network upgrade to DOCSIS 3.1 in our continuum market and increased our availability of 1-gig speeds to 62% of our total service addresses, up from 55% a year ago. We also continue to see positive trends in our broadband penetration rates for markets that have been fully launched for more than 12 months, and we still anticipate 40% to 50% consumer penetration in a steady state.
On Slide 20, you can see the broadband connection growth across all markets. Total broadband residential connections grew 6% in the quarter as we continue to fortify our networks 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 market. Shown on the graph on the right, we continue to see demand for greater broadband speeds, with 67% of our customers taking 100 megabits per second or greater, up from 62% a year ago. Our 1-gig product, along with our 2-gig product in certain markets, are important tools that will allow us to defend and win new customers.
In areas where we offer 1-gig service, we are seeing 21% of our new customers taking this superior product compared with 17% a year ago. Our focus on fast reliable service has generated a 10% increase in total residential broadband revenue.
On Slide 21, total operating revenues increased 1% year-over-year, largely driven by growth in residential revenues, which increased 4% across all markets. As shown in the chart on the left, expansion market revenues have increased year-over-year, following the timing of service address delivery. Residential wireline incumbent market revenue was flat year-over-year due to growth in broadband connections, offset by a decline in video and voice connections. Cable residential revenues grew 3% due to an increase in broadband connections. Commercial revenues decreased 6% in the quarter, primarily driven by lower CLEC connections, and wholesale revenues decreased 2%. Overall product mix changes drove a 2% increase in average residential revenue per connection.
Let me sum up the combined financial results for the quarter as shown on Slide 22. As we just mentioned, revenue increased 1% 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 were flat year-over-year, with increases to support current and future growth offset by savings in our platform costs. As a result, adjusted EBITDA improved 3%. Capital expenditures increased 50% from last year as we continue to increase our investment in fiber deployment and focus on broadband growth.
Moving to Slide 23. We have presented guidance, which is unchanged from what we shared in February. We continue to progress on our fiber deployments in new markets which, as a reminder, will put pressure on adjusted EBITDA during the year as reflected in our guidance. I want to thank all our team members for their continued dedication to our ambitious growth agenda. We have had a successful start to the year and look forward to updating you on the second quarter.
Now I will turn the call back over to Colleen.
