maybe because CRT tube does not allow widescreen![]()
i was Talking about LCD there not CRT and infact widescreen CRT were made but were very costly and bulky ..since with CRT the length of tube increases as well if u increase the screen size

and widescreen is in the market for different reason cos they are much cheaper to manufacture than a 4:3 format
the above was quite some time ago but it so happens that widescreen is much more cheap to manufacture even for higher screen sizes ...and this also gives an advantage as movies and videos in widescreen can be watched gleefullyThen, you have to keep in mind that LCDs are manufactured using a process that's very similar to the one used for semiconductors. Glass substrates are printed using lithography, depositing the TFT transistors onto the glass. It's easy to see that the more displays that can be made from a sheet of substrate, the lower the unit price will be, since the cost of the sheet of substrate is divided by the number of displays. And that's just where wide 19" displays have an advantage. On a fifth-generation substrate, measuring 1100 mm x 1300 mm, the AU Optronics, Samsung and Innolux fabs can make nine 19" monitors in 5:4 format or twelve wide-format monitors with the same 19" diagonal. That's why 19" wide panels are less expensive than standard 19"ers.
