As it has in past years, NAB Show will be flashing a little bit of star power. Both “Wheel of Fortune” and “Jeopardy!” will be honored Monday night when hosts Pat Sajak, Vanna White and Alex Trebek, along with producer Harry Friedman are inducted into the Broadcasting Hall of Fame. ABC Good Morning America co-host Robin Roberts will receive the NAB Distinguished Service Award, and television and film actress Kristen Bell will receive the TV Chairman’s Award.
