The mission: Your story in Chelmsford

It’s the summer of 1920. Engineering and electrical companies are thriving in Chelmsford, not least Guglielmo Marconi's wireless company. 

A few days ago, the UK’s first public entertainment broadcast was made from here and it's caused quite the storm. As a Fleet Street reporter, you’ve been tasked to write a feature about Guglielmo Marconi and this famous broadcast. 

You've come to Chelmsford to understand more about the man who made it happen... and why it happened here.
