Did This Week and Reporters convert to 14:9 during the flags?
Yes. In 1998 along with news bulletins.
When was 24 Hours axed? I knew Correspondent was still in 4:3 that time although others (including World News and TWT) had gone 14:9. Also when BBC World relaunched in 2000, the old DOG
still appears during ad breaks and other 4:3 programmes. That only lasted a few months until the 14:9 DOG was then used on ad breaks.
Slightly off topic, but did HARDtalk kept the old 1997 look even after World relaunched in 2000? I think this was the first programme to air widescreen as N6
was in 4:3 when the National News used it then.
