New technology makes commercial espionage easier than ever. Justin Rowlatt interviews corporate spy-catcher Crispin Sturrock about the scale of business espionage and what companies can do about it. We speak to Matt Eldridge the man behind a new gizmo, an "emotional spell-checker" which checks the tone of emails to ensure that they don't express too much anger or sadness. Is this just a solution to a problem we didn't know we even had? And James Srodes tries to experience Christmas entirely online. He tells us how it went.
