10-nanometer process technology contributed 10% of total wafer revenue during the third quarter, up from only 1% in the second quarter. The combined revenue from 16 and 20-nanometer accounted for 24% and 28-nanometer was 23%. Advanced technologies, defined as 28-nanometer and more advanced, accounted for 57% of total wafer revenue, up from 54% in the second quarter.
New advanced technologies such as voice recognition, on-device AI, AR, VR, 4G to 5G, et cetera, are driving silicon content for smartphone to continue to increase. We also see those high-end features continuously proliferate to mid, low-end smartphones.
The AI will be a fast growth, because in the datacenter it is a closed ecosystem. Once it goes to the client edge, it’s an open system. So innovators will come in easily, so has higher growth potential.
On the FCA, BMW, Intel, et cetera partnership, we’re contributing both capital, resources. We’re a full participant in the venture. So it’s going to cost us some money, it’s built into our R&D plan. But it’s the safest bet, the safest way for us to get into that market. We’re doing it with a reputable organization and there are reputable suppliers at the table too. So, I think we’ve put that issue to bed.
And there was a big issue. I’ve read a couple of the comments that people continue to make which I think probably reflect a very poor understanding of the state of the industry. But we’re not laggards here, we had just chosen our spots very carefully before we started playing, because I think that you can destroy a lot of value by chasing your tail in autonomous driving. We wanted to make sure that we did it with the right people.
And I don’t want to start chasing rainbows here, because if you chase rainbows, you’re going to fall off the cliff. And I’ve seen enough ridings now, I’ve seen enough sort of accusations of being behind in this rat race. The reality is that this is going to require a lot of discipline and a lot technical knowhow, which will take time and it will take dedication and perfect execution to get to an answer. Don’t believe the fluff, let’s just stick to the knitting and deliver an outcome, there is no shortcut to this.
Certainly in the case of Alfa Romeo the question of getting distribution because we have very little on the ground. So I think there’s a huge amount of work that needs to go on to get coverage, geographical coverage in China. And that started, it’s underway, and I think it is going to require – certainly it’s a multi-year project as it is here in the United States because this thing is starting from nothing. We haven’t had sort of the ability to work ahead of the curve in the U.S. The China is behind in that development, but I think we will – it will quickly catch up.
There is – the question that you’ve asked about whether demand is matching our expectations in China. The answer is fundamentally, yes. We need to be very, very careful that this distribution exercise, that we don’t end up creating either perceived or actual oversupply in the market that will depress pricing. That is something that we cannot afford to do.
I think over time, you’ll see more cooperation and working together between AmazonFresh, Prime Now, and Whole Foods as we can explore different ways to serve the customer.
The head count grew 77% year-over-year in the quarter. That includes the impact of the Whole Foods and Souq acquisitions. Without those, without that head count, the base Amazon grew 47%, which is still up from 42% in Q2. So a lot of the additional pickup in Q3 was tied to our ramp for the holidays. We continued to hire a lot of software engineers. We continued to hire a lot of sales reps and it’s tied directly to our major investment areas of AWS, Prime Video and devices.
YouTube now has over 1.5 billion users. On average, these users spend 60 minutes a day on mobile. But this growth isn’t just happening on desktop and mobile. YouTube now gets over 100 million hours of watch time in the living room every day, and that’s up 70% in the past year alone. YouTube Red, our first foray into the subscription market, is on track to release over 40 original shows this year and YouTube TV, our live TV subscription service, continues to expand into new markets. It now covers two-thirds of U.S. households and is available in 15 metro areas.
While mobile has given rise to an unprecedented amount of data and complexity for advertisers, we think that machine learning will help it make – will help make it easier for advertisers to reach consumers. But even as we give advertisers incredible scale and reach across our ad platforms, we know consumer attention is scarce. That’s why we are pleased YouTube ads continue to deliver the highest viewability rates in the industry. YouTube now has a 95% ad viewability rate, which is significantly higher than the average 66% viewability rate of other video ads. We continue to see the industry shift to six second bumper ads and so greater adoption this quarter.
Early in the quarter, we closed the Mobileye transaction a full four months ahead of schedule. So far this year, Mobileye has won 14 ADAS [Advanced Driver Assistance Systems] designs across 14 automakers, a pace well ahead of the 12 wins they recorded all of last year. These designs provide for typical features like automated emergency braking, lane keeping, and adaptive cruise control. But several also include next-step functionality like highway autonomous driving. We’re also winning marquee designs for Level 3 and higher levels of autonomy, including our strategic partnership with BMW and Fiat Chrysler.
Most recently, we announced that Waymo’s newest vehicles, the self-driving Chrysler Pacifica Hybrid minivans, feature Intel-based technologies for sensor processing, general compute, and connectivity. With 3 million miles of real-world driving, Waymo cars with Intel technology inside have already processed more self-driving car miles than any other autonomous fleet on the U.S. roads.
Intel and Mobileye provide the auto industry with unmatched product breadth, the architectural flexibility to support open and closed implementations, and technology leadership. Our progress in just a few short months illustrates the benefits of our combination. And together, we can deliver the promise of autonomous driving in a safer, collision-free future.
In Q3, Microsoft announced that it would use our 14-nanometer Stratix 10 FPGAs for its accelerated deep learning platform that’s code named Project Brainwave. And as part of a broadening engagement between our companies, Alibaba is using Intel FPGAs to power the acceleration of the service of Alibaba Cloud. We’ve made tremendous progress in AI and advanced computing technologies over the last few months. In addition to our FPGAs and autonomous driving wins, we launched the Movidius Myriad X, the world’s first vision processing unit with a dedicated neural compute engine to deliver artificial intelligence capabilities to the edge in a low-power, high-performance package.

I think Howard Marks describes it best in his recent cautionary memo There They Go Again, Again, which portrays the current investment environment as excessive and ripe for a correction due to the following reasons. It’s an environment where the uncertainties are unusual in terms of number, scale and insolubility, where prospective returns are just about the lowest they have ever been, where asset prices are high across the board and where pro-risk behavior is commonplace. It’s impossible for us to predict what will catalyze the market’s correction, how severe it might be and when it will occur. We are not however waiting around for fat pitches and we continue to look for attractive investment opportunities in select areas including industries experiencing stress or competitive issues.
Management fees in the third quarter declined by $8 million or 4% from the same period a year ago and were down 6% year-to-date. As was the case in the first two quarters of the year, these declines were driven by our closed-end funds where we have been a net seller of assets given the current investment climate. In this environment, our management fees have been pressured by realizations reducing the cost basis and therefore management fee basis of funds in liquidation, and slower deployment impacting the management fees of funds that charge on drawn capital and delaying the start of the investment period for funds that charge on committed capital. However, this same environment provides an attractive backdrop for growing the value of our net accrued incentives and our balance sheet investments, which bodes well for future distributable earnings.
