Do you remember those old portable pocket tvs? I remember those, but have not seen one of those in ages. I actually was not aware they went that far back to the 60's. I always thought they were invented in early 70's. This site has a short history of pocket television with an image of each model attached to it. There is also an ad for most of these tvs.
The image above is from 1963 I think (I am not positive about that part).
The Short "History" Of Pocket TV
*I forgot to mention that you may want to start reading from the main page as well. There are additional short chapters related to hand held tv.
