2007. Please refer to note 1 of our consolidated financial statements included elsewhere in this annual report for description about the  control relationship between the parent company and Senao. Our investment in Senao enhanced our mobile handset distribution and  sales capabilities. See “Item 7. Major Stockholders and Related Party Transactions—B. Related Party Transactions” for a discussion  of the agreement between the parent company and Senao about our business cooperation.  Our mobile other services include information and communication technology services, corporate solution and bill handling  services.  We have experienced continued growth in our internet services. Our internet business includes HiNet, our internet service  provider, internet value-added services, or VAS, data communication services, internet data center services, and internet other  services. Our internet revenues represented 11.9%, 12.1% and 11.4% of our revenues in 2009, 2010 and 2011, respectively.  We are the largest internet service provider, or ISP, in Taiwan, with a market share of 68.6% as of December 31, 2011. As of  December 31, 2011, HiNet had approximately 4.2 million subscribers. Our HiNet internet service generated revenues of NT$17.3  billion, NT$18.2 billion and NT$18.0 billion (US$0.6 billion) in 2009, 2010 and 2011, respectively.  The following table sets forth HiNet’s subscribers as of each of the dates indicated.  Our HiNet portal at www.hinet.net provides value-added services to our customers, such as network security, Blog, travel,  games, e-learning, financial information, music, video, anti-virus and links to other portals. We charge fees for some of these services.  We also receive commissions for transactions completed on some of these other portals. Our internet video portal at www.hichannel. hinet.net offers online entertainment services through the internet. In particular, our HiNet broadband (ADSL and FTTx) subscribers  can access music, television programs, movies and other multi-media content on demand. We charge access fees for some of this  content. We expect the revenues generated from these value-added services to grow as a percentage of our total internet services  revenues.  We have maintained our leading market position despite a highly competitive market with over 183 internet service providers  in Taiwan. We expect the competitive conditions currently prevailing in the internet service provider market to continue to intensify.  (1)  Based on data provided by the National Communications Commission.
