Okay, thanks, Shawn. So I'll go on into a little bit more depth on what's going on in each of the business segments, and we'll start with the Satellite Services. The theme there is steady progress. We're making good progress in refining our approach based on what we learned. In a minute, I'll show you some really interesting data on how we're doing in the broadband market as a whole, which lends some context to the subscriber growth data.
We're still making sequential improvements in gross and net adds. Unit economics continue to be in line with our plans. As expected, last quarter was the bottom for us in terms of earnings in this segment and this quarter, we turned about $8 million of revenue growth into about $5 million of adjusted EBITDA gain.
The chart of the -- the chart at the bottom of this page shows how our subscriber base and adjusted EBITDA have trended over the last 6 quarters, and it can give you sense of the rate of growth that's associated with current trends and subscriber additions. Adjusted EBITDA margin will fluctuate from period-to-period primarily as a result of marketing initiatives, but generally, we believe will trend in line with our models.
ARPU continues to trend up, driven by the stronger market position of the service and a higher retail mix. We're steadily overcoming the fixed cost increase of the ViaSat-1 network expansion based on the unit subscriber economics. Data continues to substantiate that we are growing from the underserved as well as the unserved broadband customer base, which suggests that we have a market opportunity that is far larger than the capacity of ViaSat-1 and the Echo satellite.
Our subscriber metrics with the Exede service shows some steady growth relative to our first fiscal quarter. Installs grew to around 71,000. The number of migrations of existing legacy subscribers on to the new Exede services declined slightly, but that meant a greater share of the installs went towards new gross adds.
In the second quarter, retail adds continued to be significantly greater than wholesale. The shift towards retail subscribers continued to yield growth in blended ARPU for our subscriber base. The churn rate in the second quarter was pretty similar to the first quarter. We've got 2 specific initiatives underway that we believe will help drive the churn rate more towards what we've achieved in the past. That would be improving the legacy service and increasing awareness of the new Exede options. The term rate really had been driven by the legacy subscriber base.
Net adds showed sequential improvement again in the second quarter. We have a number of activities underway that we believe create opportunities to increase quarterly net adds, including adding new value-added features to the service, continuing to improve our go-to-market plans and more active promotions with satellite TV.
In the next couple of charts though, we'll show that in the overall scheme of things that we're doing pretty well in net subscriber growth compared to the broadband market in general. And that the current growth trajectory is pretty consistent with our original investment targets for ViaSat-1 when all factors are considered.
So this chart gives some overall industry context for the growth rate for our consumer Internet services. The data is from the Leichtman Research Group and it shows net broadband subscriber growth for all the major cable and telephone companies, as well as for ViaSat for our second calendar quarter, that's the June quarter, and that's the latest quarter for which all of these industry results are available.
As national broadband penetration has increased over the last several years, the rate of industry growth as a whole has slowed considerably. In the June quarter, net broadband adds for the industry group that's shown here which accounts for the vast majority of total broadband subscribers, was less than 0.5%. We're about 250,000 net adds out of a base of about 80 million.
In contrast, we grew about 5% in the June quarter so we added 20,000 net based on, at that time, a base of 385,000. So that was in the June quarter. None of the major cable or telephone companies grew by more than about 1%. That's pretty much independent of size even for the several ISPs on this chart that have around the same number of subscribers that we have.
The telephone companies as a whole, actually lost net subscribers. The higher-speed fiber services like fiber-to-the-home, fiber-to-the-node, UVerse, FiOS, those grew but those gains were more than offset by a loss of lower-speed ADSL customers. In general, subscribers switched away from lower-cost, lower-speed services to higher-speed, higher-priced ones that deliver better value in a more megabits per dollar of subscription cost since.
Those trends are good for us as our research shows that Exede is a very good value compared to alternatives in terms of megabits per second per dollar. While Leichtman Group hasn't yet published comparable data for the September quarter, we do know results for the largest providers. Comcast, which accounted for the majority of industry adds in the June quarter, grew by about 1.5% in the September quarter. Time Warner Cable grew by a little less than 1%, and AT&T and Verizon both showed the same trends in the September quarter as they did in the June quarter, where migration to higher-speed, higher-priced fiber services increased, but with losses in the DSL customer base yielding a net decrease in total subs.
ViaSat grew by over 5% in the September quarter again. So in this context, our rate of sub growth is very good. Just after the end of our second quarter, HNS brought their ViaSat-1 look-alike satellite into service. It's been in service now for a little over a month, and that's probably too soon to draw definitive conclusions about the long-term competitive dynamics. But based on what we've observed so far, we believe that our growth prospects given this competition are still consistent with what they seem to be before the Jupiter launch, and that we can still make improvements in subscriber additions compared to what we've experienced so far.
So that leads to the next key question, which is even if we are growing faster than the industry as a whole, is that growth rate good enough to provide the return on capital we're aiming for when we started the ViaSat-1 project almost 5 years ago? So to answer that question, we really like this chart from the Sanford Bernstein Research report on the voice, video and data markets in the United States. Telecom is very capital-intensive and the chart shows the range of return on invested capital for wireline, wireless, cable and satellite service providers in their respective markets.
Obviously, not all providers compete in all the markets but it's easy to see the attraction of the satellite business -- satellite television video business compared to other transmission media. Essentially, satellite TV provides a competitive video service with higher return on invested capital than any other. We think the root source of competitive advantage for satellite is that it can provide a comparable service with much lower capital cost per home passed and capital cost per home served. And that's pretty much exactly what we're aiming for with our Exede broadband service, a competitive, high-speed Internet service for the unserved and underserved markets at relatively low capital cost for potential and actual subs.
Ultimately, our return on capital is driven by several key factors: the net subscriber ramp rate; our ARPU, reflecting pricing and market position and retail wholesale mix; and the cost of acquiring and keeping subscribers plus the performance of adjacent markets like it in-flight Wi-Fi or defense.
While for competitive reasons, we won't give exact numbers, what we're aiming for were returns that are sort of in the cable and satellite range that are shown in this chart. There have been significant events since we started the project in 2008. Satellite construction was delayed for over 9 months. HNS bought a look-alike satellite from SS/L. EchoStar then acquired HNS. The delay in launch made it harder to preserve our legacy subscribers.
On the other hand, we've been more retail-centric, which raised our ARPU significantly. We've shown good success in appealing to the underserved market, which increases our target market substantially. And there seem to be clear industry trends towards higher speeds and higher prices at better dollars per megabit per second, and those play well for us. Our unit economics have been pretty much in line with our plans and we've had good success in key adjacent markets for mobile services that need higher grades of service and yield better returns on the bandwidth.
The upshot of all these effects is that today, just over a year post-launch, we anticipate returns on capital that are in line with our goals when we started 5 years ago. Those returns are in between the cable and satellite companies. We believe we've retired a lot of risk and our current borrowing costs reflect that. But we think that as we scale the business, enabled by targeting a larger market, we can start to see prospects that are closer to the satellite TV space.
One of the key enablers would be a series of new satellites that provide even better economic returns than ViaSat-1, and we'll talk about that in a few minutes when we update you on ViaSat-2.
So now we'll switch to our Government segment and that had a fantastic quarter, as you can see from the data on this chart. Year-over-year revenue increased by almost 25%. Operating earnings grew from $14 million to $24 million, up about 70%; and adjusted EBITDA grew from almost $21 million to about $31 million or just over 50%.
Second quarter orders were $174 million, which represents a book-to-bill for the Government segment of almost 135%. So we added significantly to our backlog and you can see that year-over-year, the services portion of our Government business grew from about $17 million to about $45 million or over 160%. As we've pointed out before, our Government business can be pretty lumpy, driven by the timing of government contracting activities and budget uncertainties. But this quarter, lots of things lined up in our favor. Some of the performance this quarter was due to realization of revenues and earnings that were delayed from prior periods, but the strong order flow is indicative of underlying strength and growth prospects.
Some of the key growth drivers are continued success in our government global mobile broadband business, initial deployments in bandwidth services for Blue Force Tracking, as well as good performance in satellite modem and terminal products, active data links and secure networks.
Results were also very good in the Commercial Networks business. Revenue grew from about $64 million to $86 million on a year-over-year basis, up almost 35%. Adjusted EBITDA more than doubled from $1.8 million to $4.8 million. We've been very successful in capturing the most significant Ka-band broadband ground networking infrastructure programs in the world.
The Australian National Broadband Network project is an excellent example. We believe the number and scale of projects we're doing here creates meaningful competitive advantages. The chart at the bottom shows data that was compiled by Akamai for average Internet speeds on each continent, and then we compare that to the Exede 12 plan offered on ViaSat-1. We think delivering reliable speed at a good value is clearly a source of competitive advantage in most all global fixed broadband markets.
And while we realize there are many areas that are well served in most countries, there's much less cable infrastructure than there is in the U.S., and we think satellite can compete very well in underserved markets that are more dependent on ADSL and mobile wireless. But the key gating item in each market is to identify a go-to-market strategy that promotes satellite as a better choice than those terrestrial solutions, instead of just as a last resort that has to be priced at the bottom of the market.
That's still a controversial and often contentious value proposition in most of the world, so it will take some time to realize the potential there. Meanwhile, our success in both government and commercial satellite services is driven by pushing the state-of-the-art in networking technology and this business segment contains the engineering resources that do that through R&D.
We've been encouraged by the prospects for a number of areas, including advanced consumer broadband features, in-flight Wi-Fi, satellite news gathering, live online event streaming and others. So we're continuing to invest more. We also feel that we are certainly providing the benefits of achieving industry-leading results in satellite bandwidth economics so we continue to invest there too. Those investments show up in this segment and we're still showing a modest operating loss for the segment, although smaller on a year-over-year basis. We believe the investments will be worthwhile.
So that gives an overview of business segments. We think the big surge in new orders, the associated backlog, the steady growth of the consumer business and overall program performance mean we have the ingredients for sustained growth over the next few years. The trick is in balancing the strategic and tactical view so we'll spend a little time on our thinking here.
In the Satellite Services segment, we're steadily gaining experience and confidence in understanding how our high-speed service plays in the underserved markets. While nobody wants to fill up the satellite faster than we do, we want to take advantage of our available capacity and bandwidth to refine and perfect understanding that will scale to multiple satellites and create an enduring business that can achieve the types of return on invested capital the satellite TV business has in the broadcast market.
So that's where we've been aiming and the data's encouraging. The year post-launch, it looks less like we're tapping into pent-up demand in the unserved market and it looks more like we have a real and much larger opportunity including the underserved market.
Pretty much each quarter, we're trying new and different market research and tests to better understand how to identify, reach and capture those customers that are the best long-term fit for our service. We believe we're making good progress in learning a lot fast, much of which we just couldn't have learned without actually being in service.
We're very focused on unit economics that build value. We're gaining traction in the adjacent markets, and we've got our sights set on achieving cash flow breakeven in the Satellite segment around the end of this fiscal year.
All things considered, we believe we're on a trajectory to earn the returns we aimed at almost 5 years ago, and that we're doing well in the context of the overall U.S. fixed broadband market. Our Government Systems business continues to perform really well in a very, very challenging environment. It seems that the tightening budgets are making government customers much more price conscious and willing to try new things, which is good for us compared to the larger defense primes.
The value of good intel, surveillance and reconnaissance data and the ability to communicate and disseminate it is recognized. We have unique capabilities to offer and we believe that's reflected in our results. We also think that we've barely scratched the surface of what's possible with satellites such as ViaSat-1, so there's good long-term growth opportunities.
In the short term, we're not going to be able to reproduce quarters like this every period, but we think it's becoming more clear that we can grow revenue and earnings on a year-over-year basis this year and next fiscal year and target doing so on a continuing basis.
We think our unconventional approaches will play well in a time of constrained programs of record. Likewise, our Commercial business is benefiting from a leadership position in Ka broadband.
Our backlog creates confidence. It is important to note that we believe much of our competitive advantage comes from our leadership position with the ViaSat-1 satellite, so we're working hard on extending that leadership position with ViaSat-2.
We're still working on finalizing the ViaSat-2 procurement contract. We're choosing from 2 very competitive options. Both those options should enable us to achieve our strategic objectives of improving band with economics, reaching the entire United States and extending into some important new geographies and markets.
We anticipate we'll be under contract this quarter. We believe we have the capital resources in place and we'll talk more about ViaSat-2 when we announce that procurement contract.
So that completes our prepared remarks. Before we take questions, I also want to talk for a minute about our first ViaSat Analyst Day, which is scheduled for November 29. We think it'll be really worthwhile, allowing us to go much greater depth on markets and strategies than we can on these quarterly calls. We'll have more data and insight on the overall consumer broadband market and the factors that are driving and helping our competitive positioning. Plus, we'll be able to give greater depth on our government and commercial adjacent broadband satellite markets.
So that's it, and now we'll open it up for questions.
