American High, the documentary series that follows a senior class, including gay student Brad, through the last year of high school, has become a hit on PBS. The show had an abbreviated run of four episodes on Fox last year but is proving highly popular this time around, both during its Wednesday night airings and as a Web site (www.pbs.org/americanhigh). The site features bios, videos, and transcripts of interviews with each of the participating students, in addition to an "interactive yearbook" and updates on what the graduates are doing now. The shows underwriter, Coca-Cola, will also be holding town hall meetings in Philadelphia, Atlanta, and Chicago as a forum to promote communication among teens, adults, and educators. The president and CEO of PBS, Pat Mitchell, said, It was our hope that this compelling series would create a national dialogue about the issues that teens are facing today. Were very excited that the broadcasts...have sparked powerful responses among viewers of all ages and walks of life. Check local listings for show times.
