Those of us of a certain advanced age will remember how back in the 1960/1970's the UK was flooded with electronics products mainly of Japanese origin that knock some of our own home brands for six. Names like, Bush, Goodmans, Echo Pye, Ever Ready, . with technological onslaught from the Japanese manufactures some of own brands simply disappeared and we became familiar with brands like Sharp, Hitachi, Sansui, Panasonic, Trio etc But amongst these names were some stronger established brands such as Philips, Grundig, Telefunken, whose names seem to have survived, but if you look deeper into the brand wars, you will see how many of these names were often taken over or combined into a bigger groups, and over a few years some names disappeared from general sale.
But some names have reappeared in recent years usually on the shelves of discount sellers, and again if you look into the details you'll find for example the Ever Ready (Batteries) name is now owned by the owner of B&M stores along with several other heritage brands.
Also if you look carefully at many of the cheaper TV's on the market you will find many of them are identical, and in fact these cheaper TV's are simply badge engineered products, and the name does not represent who has manufactured the product, but it has either been bought or licenced by mass low cost producer to give the impression their product might have a better pedigree than it actually has.
A similar fate has fallen on some of the well respected Japanese brands, Trio, Kenwood**, Marantz, Onkyo , Pioneer.
--Trio products were not selling well in the USA, so the importer pushuaded Trio to brand their products as Ken Wood (A more american name)
I know from practical experience, that a friend had a BUSH branded TV purchased about 12 years ago. It failed out of warranty and I did some fault finding and found the faulty subassembly and replaced it. a couple of years later the screen was smashed, so a neighbour offered my friend her old Sharp TV. It was exactly the same model in every detail except for the branding. I later discovered the exact same model in a "pre loved" shop brands as a Toshiba.
Don't assume becasue a TV carries a well respected name from the past that it will have the quality and features associated with that name.
Names that may have had a proud history, may still be seen on the shelves but the product may have no connection to the history of the name. There are only a few brands of TV that retain a distinct link to their heritage, such a Sony, Samsung, LG, there may be a few others but notably Philips who had been a top spot TV manufacturer up until the turn of the century, today their name has been licenced to an little known maker who I believe often uses LG screens in their sets.
