Patrick Stewart, who has amassed nearly 750,000 followers on Twitter, says the social networking site has given his acting career a new boost since his days as "Star Trek" Capt. Jean-Luc Picard.

During an interview from the New York Stock Exchange on Thursday, Stewart, who is relatively new to Twitter, told CNBC the micro-messaging service had become a big part of his life.



"An obsession might be a little strong a term, but it has now become one of the most significant aspects of my life, but most importantly of my career, because it has changed the public's perception of who Patrick Stewart is," he said.
