during 2016 , sohu video began to shift our focus to the self-developed content category , which , in our view , will create long-lasting value to our platform and offer better financial returns compared to tv station content . leveraging our exclusive original content , we also actively explored opportunities with subscription services that we believe will become an important revenue source in addition to traditional advertising revenues . financially , sohu video 's revenues for 2016 were affected by the weak economy and a turnover of the video sales team in the middle of the year , and its loss-making widened from 2015. for our search and search-related business , sogou is one of the top players in the online search sector in china . we have reinforced our competitive position

in-game promotions , improving in-game content and strengthening social functionality . the revenues of tlbb remained stable throughout the year , with slight increases in the third and fourth quarters on a sequential basis . for changyou 's mobile game business , revenues from tlbb 3d declined sequentially mainly due to its natural declining life cycle . in order to extend the game 's life span , changyou will explore new social interactive features that can be added to the game . overall , changyou started at the beginning of 2016 to focus on producing high-quality games . this approach and higher testing standards have set the bar high for new games in the pipeline , which had an impact on 2016 revenues . nevertheless , after a year of hard work , changyou now has a solid
