Thanks, Huang. Thank you to everyone for joining our call. Under the current challenging macroeconomic environment, our total revenues stayed largely in line with our prior guidance. Our bottom line performance, excluding the charge for impairment of assets recognized by Changyou related to its cinema advertising business, met the high end of our prior guidance. This was mainly driven by the continued cost savings that we were able to achieve at Sohu Video, and the solid performance of our online game business. For Sohu Media, Sohu Media is making a comeback and living up to its reputation as a top-tier media platform. We've been hosting high-quality events, generating and distributing premium content, and strengthening our core competitiveness and credibility among media brands. Meanwhile, Sohu Video continues to provide users with unique high-quality dramas and shows.
We've seen the positive effects of this differential development strategy and stable improvement in monetization at both Sohu Media and Sohu Video. We hope to see further progress in the coming quarters. In the second quarter of 2019, Sohu achieved steady growth in its core search business while Sogou Mobile Keyboard further expanded its user base and reinforced its position as the third largest Chinese mobile app. For Changyou, both its revenue and profit exceeded expectations, excluding the aforementioned charge of impairment. Changyou is demonstrating a stable profitability while developing more eight games to provide a diversified product portfolio. Before I go into more detail about the key businesses, let me summarize our financial results for the second quarter. Total revenues, $475 million, down 2% year-over-year and up 10% quarter-over-quarter.
On a non-GAAP constant currency basis, total revenues would have been $32 million higher than our reported revenue, which would be a 4% improvement year-over-year. Net brand advertising revenue was $44 million, down 29% year-over-year, and up 2% quarter-over-quarter. Search and search-related advertising revenues, $276 million, up 2% year-over-year and 18% quarter-over-quarter. Online game revenues, $102 million, up 8% year-over-year and 6% quarter-over-quarter. Operating loss for Sohu Video was $23 million, compared with a loss of $35 million in the second quarter last year, a 33% improvement. GAAP net loss attributable to Sohu.com Limited, $53 million, compared with a net loss of $48 million in the same quarter last year. Non-GAAP net loss attributable to Sohu.com Limited was $50 million.
If excluding a charge of that impairment asset recognized by Changyou in the second quarter of 2019 related to the cinema advertising business, non-GAAP net loss attributable to Sohu.com Limited was $38 million, an improvement of 22% year-over-year. Including Sohu and Changyou, non-GAAP net loss attributable to Sohu.com Limited was $68 million, an improvement of 15% year-over-year. Let me go through some of our key businesses. First, media portal business. As I mentioned earlier, Sohu Media is currently making its comeback. We are actively strengthening our influence across certain verticals such as technology, finance, and fashion. In the second quarter of 2019, we successfully hosted Sohu Tech's 5G Forum: First Year of the 5G Era, which involved industry collaborators and gained widespread discussions as well as sustained influence. In early July, we launched the fifth China drone photography contest, which will last till September.
This contest will show off a combination of technology and art, and we'll be able to generate and distribute a large amount of premium content on our platform contributed by this event. This event not only demonstrates our position as a mainstream media source, but also enhance our core competitiveness and credibility by allowing us to leverage high-quality content across our platform, which generates further interest and discussion and attracts users as well as advertisers. We are continuously focusing on ways to further improve our product and generate great content. In addition, we're also constantly refining our recommendation algorithms and building social network features and products. In the most updated versions of social products, users can reach the content they're interested in more quickly and accurately. Sohu News app.
Notably, these new features can help users track news and content they like and gather users with same interests into communities where we can comment on the topics and further interactions. In other words, we are building tools for users to contribute their own user-generated content, UGC, and also building interactive social network on the Sohu News app. Additionally, we are constantly engaging with encouraging third-party writers to produce more in-depth content around certain topics in order to further improve users stickiness. In this quarter, advertising revenues were inevitably influenced by the economic slowdown, especially in the auto and IT industries. In the face of these challenges, we work hard to diversify our revenue sources while producing abundant high-quality content with various events. This work is helping to attract advertisers and elevate our competitiveness and influence and should help us post a modest rebound in revenue in Q3.
We are also committed to strictly control our costs and expenses in order to limit the financial losses in the Sohu Media business. Moving over to Sohu Video. In the second quarter, we continued our two-engine strategy with a balanced mix of original long-form content and short clips user-generated content. We've been able to produce more and more high-quality content at a much lower cost and start a differential development strategy. We're happy to see some encouraging initial success. Sohu Video ranked number four on CI Week's online video app ranking list for the first half of 2019. In the second quarter of 2019, we were able to reduce our operating cost loss for the unit to $23 million, which was a 33% improvement from a loss of $35 million in the same quarter last year.
We plan to strictly keep our budget under control in the second half of this year and further improve the bottom line. In terms of content, we have developed a more in-depth understanding of idol women and criminal-themed dramas, the two series. We have already created brand advantages in these two types of IP and received recognition among audiences as well as advertisers. For example, Well-Intended Love, Nai He Boss Yao Qu Wo, gained widespread attention and was ranked number four by Guduo among all original dramas in the first half of this year. Looking ahead, we will start shooting the second season of Well-Intended Love and expect to release it next year. There is already considerable buzz for the show among viewers, and we have seen significant interest from advertisers.
In July, we released The Next Superstar, another popular idol romance drama, and in the second half of 2019, we'll release several criminal-themed dramas, including Without Knowing, Dawn Breaking in the East. The Next Superstar in Chinese, Re Sou Nu Wang, and Without Knowing, Dawn Breaking in the East in Chinese is the Bu Zhi Dong Fang Ji Bai. We believe we are well-positioned to continue delivering attractive and diversified content on our video platform. Next, turning to Sohu. In the second quarter, Sohu maintained its position as China's second-largest search engine. Search revenues continued to grow faster than the industry average. As of June, Sogou Mobile Keyboard DAU reached 415 million, up 17% year-over-year, and average daily voice requests made via Sogou Mobile Keyboard increased by 72% year-over-year.
Furthermore, Sohu continued to implement the AI strategy of developing language-centric AI technologies and advance its leadership in voice and computer vision with many industry-leading breakthroughs. Lastly, for Changyou, for the second quarter of 2019, online game revenue $102 million, which slightly exceeded the high end of our guidance. Revenue for PC games increased slightly quarter-over-quarter, mainly due to the solid performance of several legacy PC games, which helped to offset a decrease in revenues from TLBB PC due to its natural decline in life cycle. During the quarter, Changyou launched an expansion pack for TLBB PC's 12-year anniversary. In the third quarter of 2019, Changyou will launch a new expansion pack and introduce more new game content to sustain user interest. Going forward for PC games, Changyou's key strategy is to maintain player engagement and maximize the longevity of legacy PC games such as TLBB.
For Legacy TLBB Mobile, Changyou continued to focus on long-term oriented operational strategies and introduce new content to provide its players a better experience. In Q2, the expansion pack launched for Legacy TLBB Mobile's two-year anniversary introduced great new gameplay for players, resulting in higher user satisfaction. Furthermore, MMORPG mobile games will continue to be a strategic focus, while Changyou is developing a number of casual games and strategy games to provide a diversified product portfolio. Now let me turn the call to CFO Joanna, who will walk you through the financial details. Joanna, go ahead.

Ladies and gentlemen, we will now begin the question and answer session. If you wish to ask a question, please press star one on your telephone and wait for your name to be announced. If you wish to cancel your request, please press the pound or hash key. The first question comes from the line of Eddie Leung from Merrill Lynch. Please ask the question.
Good evening, management team. Thank you for taking my question. I would like to know if you could talk a little bit about the advertising outlook getting into second half of the year versus what we had in the second quarter. Particularly, could you also comment on the competitive landscape, which we heard have been affecting the advertising prices in the industry? Thank you.
The macroeconomic situation definitely is really the pressure over advertising, but because we have so many sectors. Certain sectors are under pressure, like auto, but there's a lot of other sectors, verticals that actually we've seen even growth. That's why for Sohu's media portal, we are planning a lot of activities, content generation activities, and some unique marketing events that attract advertisers to advertise on the Sohu platform with these premium content, so that we are able to attract. That's why, even under this economic slowdown, we are actually looking at a growth compared with Q2. Right? Yeah. For advertising. For video, same thing. For video, we have some unique drama and variety shows that have the built-in advertising. We're not competing on price, but competing on premium event or content that can be competitive in getting advertisers.
That's very helpful. Thank you, Charles.
Welcome.
Thank you. Once again, if you wish to ask question, please press star one on your telephone and wait for your name to be announced. We have the next question comes from the line of Alicia Yap from Citigroup. Please ask the question.
Hi. Good evening, Charles and Joanna. Thanks for taking my questions. I have a couple questions. Number one is related to the latest regulatory environment, and the restrictions on the TV dramas. What are the impact to Sohu Video so far, if any? Second question is related to this overall app sentiment weakness. I think Charles did mention on the prepared remarks, seems like Sohu Media, the portal, have some decent comeback. Wanted to get a sense in terms of how we should think about this into even a little bit further into next year, and what is mainly driving the more positive momentum on the media portal side. Thank you.
First of all, on the media content side, there is some regulations, from the very start in choosing the topics and also to work together with the authorities. It now has been not a problem with the release of our TV dramas. For example, like the restriction on making some dramas of the ancient times, the old stories. We now only produce modern dramas, topic, themes of modern times. Also relatively compare with the television TV dramas, they're relatively more relaxed. It's not a problem recently our Knights of X, actually, Well-Intended Love and also Rebirth For You with The Next Superstar, there's no problem to get the approval from the authorities. It's actually an interactive process with authorities to make sure that dramas get approved.
In terms of media advertising, as I said in my answer to the first question, in the premium activities or content-generated activities, for example, like our Sohu-sponsored Sohu News Marathon that involved a lot of celebrities. That's getting advertisers, because in that event, we have our Sohu Media and also the Sohu Video as a reporting media to report these celebrities running marathon. It's been a project that we've been doing it for the 10th time, 11th time actually. It's actually getting good advertisers. The other one that we just launched, the drone filming contest, which are also getting good advertisers. The forum, we have a 5G forum and also in the second half of the AI forum and the business forum. All these content-generation activities are generating premium content so that we're getting advertisers.
For this year and next, I think these kind of brand advertising will be unique, that Sohu can do, so that it's competitive. At the same time, in the long run, we hope that not only we'll continue with this brand advertising, with events or premium content-generated advertising, but also by developing a better algorithm for news app and also social network features of news app, and also the vlog and the social network feature of the social video app. Also Huyou, our social network product. Together with our large traffic from the PC side, where we accumulate over the years, and also the Sohu H5, the WAP portal, that's a lot of traffic.
With all these, in the future, we hope that our traffic increase will have the momentum, so that with larger traffic, not only with brand advertising, premium brand advertising, but also the small media enterprises, the long tail standardized advertising will also pick up. That's why with these two kind of advertising, we hope that into next year, our advertising business will be competitive.
Thank you.
Thank you. Once again, if you wish to ask questions, please press star one on your telephone and wait for your name to be announced. We have the next question. It comes from the line of Ray Zhou from First Capital. Please ask a question.
我想问一下Charles，对于我们剔除掉搜狗和畅游之外，搜狐一个季度的净现金流大概是什么水平？
你听懂了吗？好不好？你再问吧。反正值得注意的是，就是刚才我说了，第二季度这个净现金流也类似于我们剔除这个搜狗、畅游之后的它的收入。这个是$6,800万美元。这个是对于比起去年来说是一个改善，包括比起第一季度也是个改善。但是值得注意的是Q3，这个数字从$6,800万美元减到了介于$5,000万到$5,500万。所以说这个是一个major reduction。所以说这个是值得注意的。我们在business outlook里面给出一个range。我刚才就说，一方面我们通过我们这样的一些活动和一些回归媒体，media，导致我们能够得到一些premium的这种brand，一个high value的品牌advertising。同时可以获得增长，但是在获得这些DAU和user base的成本方面可以减低。一方面增长，但成本在降低，所以导致我们在第三季度能够实现这个现金流的一下减到了接近$5,000万到$5,500万。而且我们希望the rest of the year甚至Q4的话会继续降低。Got it?
Okay. Thank you.
All right.
Thank you. Once again, if you wish to ask a question, please press star one on your telephone and wait for your name to be announced. Ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
