19" "portables" and the first Sony home recordin
Our first two color tv's were 19" table top models, but they didn't have a handle on top so I guess they weren't billed as portables. The first one, a GE, we won in a Lions Club raffle. That tv came with an attractive, modern styled cart. It had a nice handy storage tray (wood) below the tv. Better yet, the existing B&W tv in the den was small enough to fit on a shelf in the built in bookcases. The color tv was too deep to fit, so had the cart not been provided, we would have had to buy a small table or something to accommodate the tv. The den had two sofas and a recliner. Depending on how many people were present in the room, the optimal viewing angle for the tv might change, and so the cart allowed the tv to move or swivel. It never left the room, but sometimes the tv position was changed depending on who was watching.
Second tv was a 19" table top Hitachi to replace the GE when it died. This was in a different home than the GE, and within a year my folks had had cabinets built into a wall of the new living room. Having a table top model was more versatile because you could hide the tv in the cabinets, something you could not do with a large furniture-style tv.
Most of the Japanese models came primarily in table top models. That makes sense, since small Japanese homes would never have room for a large US style furniture cabinet tv.
The only time I ever saw a cabinet-style Japanese tv was a huge special order Sony with two screens and videorecording capability. This was in 1976, I'm not sure if they used reel-to-reel or U-matic, but the unit did not have a removable VCR, rather the recording equipment was built into the unit. As for why the unit had two screens, I'm guessing there were dual tuners and you could watch a program live while also viewing the program being recorded (like modern VCRs, except in the latter case you toggle between the tv's tuner---live---and the VCRs tuner--what you are recording).
I saw this Sony in the home of a rather wealthy family. I worked for a furniture company over the summer and helped deliver a table to the home. I knew one of their children from school, but only the housekeeper was home that day to let us in. So I didn't get to see the Sony in action. I did see a logo on the cabinet that said "home recording system" or something like that.
