2/10: Twitter, Square co-founder on tech and retail; radio in Rhode Island

This week on Executive Suite: Jack Dorsey, co-founder of Twitter and mobile-payments startup Square; John Rooke, author of "Rhode Island Radio."

Dorsey has become a billionaire and one of the most famous tech entrepreneurs in the world after founding the megapopular messaging service. In an exclusive Executive Suite interview taped at the Rhode Island School of Design, he discusses how he wants Square to make commerce easier and why he thinks anyone can find value in using Twitter. He also describes what Rhode Island's leaders should do to spur economic development.

John Rooke, a longtime local broadcaster perhaps best-known as the voice of Providence Friars games, discusses his recently published book "Rhode Island Radio" about the local history of the medium. Rooke explains why department stores founded the first stations, what was unique about Salty Brine, and why some local community stations are concerned about the next generation.
