The amazing BBC Archive have posted a series of images of empty BBC Television sets across the years to be used as Zoom or Teams backgrounds.
You can visit the page select the background you want and then save to your computer.
Of course there are some classic (and modern) TARDIS backgrounds.
I also like the fact I could be self-isolating with Del and Rodney, well maybe not.
Then I could be in Tom and Barbara’s kitchen in the Good Life.
Or sitting at the back of a Grange Hill classroom.
Plenty to choose from.
