All TV's manufactured up to 2012 are affected, not just Sony. Google (who owns YouTube) decided to come out with a new version of YouTube through which it can support ads easier & thereby increase revenues. They have no regard for thousands of "Smart" TV owners who are tied by their hardware to the older version of YouTube. Google knew this prior to implementing the change and had in fact sent out a notice a year in advance that the old version would no longer be supported as of April 20, 2015. Your only recourse is to buy a device such as Roku, WDTV Player, Apple TV or something similar to any of these if you want to continue getting YouTube on your TV. Google's cavalier approach to this issue shows just how arrogant they have become as a business. They had to have known that people do not replace TV's for 7 or 8 years and yet the models that this decision affects are as new as 2012. Who is going to replace a 2 year old TV just to be able to play YouTube? Future TV buyers should take notice of this apathy by Google and when it is time to buy a new TV, just get a basic set. The "Smart" features incorporated at additional cost can be cut off with little or no warning by a 3rd party, and with no recourse available to the consumer.
