The Apple TV set-top box has more than 5,000 apps available since its relaunch last fall.

Tim Cook, chief executive of Apple, said in a press event today that the new Apple TV’s most popular apps include HBO Now, which lets you watch HBO shows such as Game of Thrones on the go, and NCAA March Madness. These apps have helped lead to the “largest sales ever” for a new version of Apple TV.

Cook said that Apple TV’s tvOS is now getting Siri voice integration, allowing you to make a request such as “Show me movies with Kevin Hart.” Siri can search for more apps than it has been able to do in the past. Apple is adding folders to the Apple TV interface, as well as┬ádictation for entering user names and passwords.
