The view from the top of business. Presented by Evan Davis, The Bottom Line cuts through confusion, statistics and spin to present a clearer view of the business world, through discussion with people running leading and emerging companies.

In the week that Facebook launched its own new messaging service, Evan and his panel of top business guests discuss the role of email at work, amid the many different ways of messaging and communicating.

And location, location, location. It's a cliche that location can make or break a business, but how true is it really? And what are the advantages of being next door to the competition?

Evan is joined in the studio by Chris Grigg, chief executive of property company British Land; Andrew Horton, chief executive of insurance company Beazley; Raghav Bahl, founder of Indian television news group Network 18.

Producer: Ben Crighton

Last in the series. The Bottom Line returns in January 2011.
