Virtually all of The Continuity Booth's written content moved across to The TV Room Plus in 2006. The material was incorporated into TV Announcers, TV Presenters, TV Buildings and TV Features.
Many of the images and video clips on TCB were created a number of years back, when PC hardware and software wasn't as advanced as it is now. Website hosting costs were also higher, so keeping image and video file sizes down was important. Consequently, many of the announcer/presenter images featured on TCB were very small; this was also the case for video clips. The best solution would've been to regrab the images/clips from the original video, at larger resolutions.
Unfortunately, neither I nor the TCB webmaster are yet in a position to bring the visuals back online. It may happen at some point, but at the moment, there's no timeframe for this.
