we see companies like visio or china television that was recording and storing this data.ut the deployment of the new security is much faster in these devices because they are always on, always connected . as soon as an exploit is revealed again patch it fairly quickly. the turnaround time for security fixes is even faster than computers. computers we rely on those every single day for major transactions. >> eventually i'm sure i'll get on board. ryan eldredge, i appreciate you taking the time. thanks. >> i'm not on board, i like to just open the door myself. but it is the future. >> what's amazing is how rapidly things are developing. just over a year. >>> can you imagine i'm sure there's a meteorologist on tv named alexa. alexa, what is the forecast? >> we like having you in the flesh. >> outside right now we are looking pretty good toward the estuary. there is some haze looking out toward the bay throughout the afternoon hours. still a mild afternoon. not a major warm-up just yet. it's may not be a hot forecast but still some 70s and 80s. most areas are in 70 two about

they all try to get person -- permission and there was an fcc case against visio saying tv viewing isensitive and you had to have permission, they all kind of had permission, they talk about targeted content, but you could tell that in many cases, they were definitely afraid to try to get you to hit except in the skip button was hit -- hidden in the corner. the challenges, finding a score to the user interface. the first time we did not feel comfortable picking winners or losers and we learned a lot. i have my thoughts about it but the are is a careful organization that would like to get it right, they have a history of testing things and there is a scientific process in place. i would like to say whatever justin feels like we need a more rigorous process. the goal is for the next set of ones that we will release soon to pick test and worst, to rank them, then there is a ball that one day we would feel comfortable assigning a score and it would say, this tv gets a 30 on privacy because they do not tell you that they are watching you, they do not get security up dates or get this and t
