With television sales down for the second year in a row, it seems improbable that Apple (AAPL) would enter the market. But speculation persists that Apple will make a TV one of its promised new product categories this year. Apple (AAPL) hasn’t disclosed what those new product categories will be, but CEO Tim Cook has said that television is an area ripe for innovation. Last May, speaking at the D: All Things Digital conference, Cook said Apple had “a very grand vision” for the television space. “When you look at the TV experience, it’s not an experience that I think very many people love,” Cook said. “It’s not one that has been brought up to date for this decade. It’s still an experience much like 10 years ago or 20 years ago.” Apple’s forays in the market have been limited to a $99 set-top box, confusingly called Apple TV. For years, Apple called the Apple TV business “a hobby,” but at the company’s annual shareholders meeting on Feb. 28, Cook said the company generated more than $1 billion in Apple TV sales in 2013. That implies sales of more than 10 million units last year, Re/code reported.
