Roku introduced their first ever Smart TV at CES 2014. The interface is similar to the Roku set top box but also features input buttons for Blue Ray players and Cable TV. When the user first boots up the Roku Smart TV they will see a home menu where the user can access their favorite applications such as Netflix. The Roku TV will come out later this year and it will ship in 32 inches and 52 inches. I think Roku has an advantage over other Smart TV’s because of the Roku set top box. They already have an established TV product that has done well.
