The Rise and Fall of Teletext

DirecTV (Back in the 00's) had something similar in their boxes they would transmit local news, weather, sports, and all the other basics from TeleText to their receiver boxes over their transmission satellites. The boxes had enough memory to store a ton of stuff including full color radar images for the weather that you could pan and zoom in on. It was super super slow but I found it useful even though no one else in the house knew it existed lol. This was also how their TV Guide worked. You could actually find it as a submenu under the Guide button on pre-2012 DirecTV boxes.
