The host of Latino USA for all of its 17 years, Maria Hinojosa, is now its proprietor, too, along with producer Sean Collins, her partner in a new media company in the digital cloud. Futuro Media Group, announced this month, starts off highly virtual and will get moreso. Hinojosa records her reports in a soundproofed closet in Harlem. Collins, her e.p. for five years and a former producer of All Things Considered, works in his hometown of St. Louis.
