The Academy of Television Arts and Sciences, the group behind the annual Emmy awards, paid tribute to what it called “television with a conscience” at its third-annual Television Academy Honors. Among honorees at the Wednesday night ceremony: individual episodes of “CSI: Crime Scene Investigation,” “Private Practice” and “Glee.” Former US vice president Al Gore accepted a statuette for his Current TV network's “Vanguard” series, which documented effects of prescription-drug abuse. “The fact that this award has been established by the Academy speaks so well of the Academy,” said Gore. “It really means so much to be here.” Gore also acknowledge both the journalistic and political work of California first lady Maria Shriver, who served as executive producer of the Academy-honored documentary “Grandpa, Do you Know Who I Am? with Maria Shriver,” which followed grandchildren forced to cope with a grandparent's Alzheimer's. Shriver's father, R. “Sargent” Shriver, has long battled the disease.
