NEW BEDFORD — As “Jeopardy!” continues the search for a permanent host, here’s a look back at some SouthCoast competitors and “SouthCoast-themed” questions over the show’s 37 years on television. Since the show’s inception in 1964, a few locals from the SouthCoast have had the chance to grab a buzzer to test their knowledge in a wide range of academic and popular categories. They may have had the chance to hear questions read by legendary host, the late Alex Trebek. Contestants from New Bedford include Kate Martin, a researcher and editor; Andrew Nelson, an antiquarian bookseller; Tony Barreto, a deputy district attorney, and Chris Rodrigues, a personal banking representative, who was a three-time champion ($41,498) in 2009.
