Jeffrey Tambor and Jill Soloway delivered Amazon.com its first major Emmy awards for the show "Transparent," as the online retailer went toe-to-toe with Time Warner's HBO.
HBO's "Veep" vied for top comedy prizes with "Transparent," in which Mr. Tambor plays the patriarch of a Los Angeles family who reveals to his children that he has long felt he's a woman and is going to dress like one. The face-off between the companies highlighted the growing competition between newer players like Amazon Studios and longtime leaders like HBO, which demonstrated its dominance again Sunday.
"Transparent" also won in the guest actor in a comedy series category, for Bradley Whitford's performance.
Netflix, meanwhile, took home two trophies Sunday night: supporting actress in a drama series for Uzo Aduba's performance in "Orange is the New Black" and guest actor in a drama series for Reg E. Cathey's role on "House of Cards."
Ms. Soloway created "Transparent" and won an award for directing, 1 of 11 nominations the show received. Both Mr. Tambor and Ms. Soloway called out Amazon and advocated for transgender rights in their speeches.
"I'd like to dedicate my performance to the trans community," Ms. Tambor said. "Thank you for your patience, thank you for your courage, thank you for your stories, thank you for your inspiration, thank you for letting us be part of the change."
"Veep," a parody of American politics adapted from a British satire, won three of the early awards handed out tonight, two for acting and one for writing. Julia Louis-Dreyfus won the lead actress Emmy for her performance as President Selina Meyer, her fourth consecutive win. Tony Hale won for his supporting role in the series.
Allison Janney won the only comedy Emmy that didn't go to "Transparent" or "Veep," taking home an award for her supporting role in the CBS series "Mom." The Emmy was the seventh for Ms. Janney, who has garnered awards for "The West Wing," 'Masters of Sex" and now her second for "Mom." That ties her with Ed Asner and Mary Tyler Moore for the most awards of any actor or actress in Emmy history.
