When ESPN announced an HD channel nine years ago, its executives barely knew about the Consumer Electronics Association. By the time it was ready to announce a 3D channel last year, the network elected to break the news at the association’s Consumer Electronics Show, or CES. This week at CES, it is following up by announcing that ESPN 3D will start broadcasting 24 hours per day, giving 3D television buyers more to watch. ESPN’s embrace of CES attests to the importance of the show that begins this week for media and technology companies alike. Nowhere is there a better display of the symbiotic relationship between entertainment and electronics. LA Times: Apple is nowhere to be found at CES in Las Vegas, but its shadow is just about everywhere. Many of the world’s largest electronics makers have come to the show to unveil new products aimed squarely at Apple’s popular devices, but Apple does not participate in the year’s biggest tech event. ReadWriteWeb: The Open Mobile Video Coalition, or OMVC, is presenting this year, and it has a handful of mobile TV devices to show off that will be exciting for the TV viewer on the go — especially one that retrofits all your mobile Apple devices for Mobile DTV. LA Times: RCA said at Tuesday’s CES event in Las Vegas that it would launch a line of portable TVs that could pick up both standard over-the-air and mobile digital signals. RCA’s portable viewers — a line of three TVs, along with a mobile DTV receiver to be used in automobiles — make use of the mobile DTV standard overseen by the OMVC, as well as standard broadcast channels. NY Post: Even before he kicks off the tech industry’s annual geek gathering, it seems that Microsoft CEO Steve Ballmer is late to the party. With Internet-connected TVs all the rage, Ballmer is likely to talk about “Microsoft TV” during his keynote speech Wednesday night at CES. Microsoft is reportedly working on a pared-down version of Windows that will run on set-top boxes and Blu-ray players. Ballmer’s entry will follow Apple TV and Google TV, with the new Windows TV boxes rumored to cost a hefty $200 a pop. Microsoft has had a run at this sector before with a similar concept named WebTV.
