Good news for Google Fiber subscribers who want to follow the adventures of Tyrion Lannister and the Stark family: Google on Tuesday announced that its Fiber television service will now offer HBO for an additional $20 per month. The entire $20 monthly package includes not just HBO but also HBO2, HBO Signature, HBO Family, HBO Latino, HBO Comedy, and HBO Zone. A similar Cinemax channel bundle is also now available for $10 per month. Google has been slowly working to add more channels to its Fiber television service to compete with cable operators such as Time Warner Cable by delivering both a comprehensive pay television service as well as the fastest broadband Internet service in the United States.
