Jim Parsons has won the 2014 Primetime Emmy Award for Outstanding Lead Actor in a Comedy Series for his performance in the hit CBS sitcom "The Big Bang Theory."

The 41-year-old actor, who plays the role of nerdy Caltech physicist Sheldon Cooper in the Chuck Lorre and Bill Prady-created series, beat Louis C.K. ("Louie"), Don Cheadle ("House of Lies"), Ricky Gervais ("Derek"), Matt LeBlanc (Episodes) and William H. Macy (Shameless) in the said category, Huffington Post reported.

This was Parsons' fourth Emmy win, as he previously won the same award for the same role in 2010, 2011 and 2013. He was also nominated in 2009 and 2012, according to The Associated Press.

In a video of his acceptance speech posted by PerezHilton, Parsons said that he has been watching the works of his co-nominees and that motivated him to improve his craft even more.

"To say that I watch your work and I feel inspired is a little bit of an understatement," he said. "And I see you doing things that I couldn't do. I see people doing things that I wouldn't do. I see people doing things in all seriousness that are so divergent and all over the place. And all of us doing such different things that I do pray to do one day - that's the landscape we live in - is a long way of saying that there's no accounting for taste."

Then he expressed his gratitude to Warner Bros. and CBS as well as to the Lorre and Prady.

At the end of his speech, he gave thanks to his father, who he said he has never thanked in the past.

"I wanna thank somebody that I've never thanked before largely because he passed away shortly before this craziness started even though I think he was able to see it on his own way. It's my father Mickey Parsons," he said. "He encouraged me to be an actor. He never discouraged me to be an actor and [to be] in a career that hinges so much in confidence, a lot of the time, that was a really great gift, so I thank him."

Aside from his "The Big Bang Theory" win, Parsons was also nominated for supporting actor in a movie or miniseries for his dramatic role as gay activist Tommy Boatwright in HBO's "The Normal Heart," the Los Angeles Times reported.
