This Blue Plaque was recently mentioned by William Gibson in an interview with Steve Ranger of silicon.com:
"There's a blue plaque in London that says, in effect, 'Broadcast television was invented here'. Nobody in that room above the shop was filled with a kind of eldritch horror and a vision of a world of closed circuit surveillance - it was the last thing they were thinking."
