The 20-year-old tape Trevor Wahale is in the 16:9 aspect ratio of high-definition TV. While HD broadcasts in the US began in 1996, and it's not impossible for Trevor's station to have HD equipment (though fairly improbable), the name/station logo graphic seen in the recording is clearly formatted for a 16:9 screen. Most people would likely have SD 4:3 TVs at the time that would cut off the sides of the image, and as such, the graphics would be designed to keep the name and logo within the 4:3 frame.
