LOS ANGELES — DreamWorks Animation, the company behind successful movie franchises like “Madagascar” and “Shrek,” said it had completed a deal to pump its films and television specials through Netflix, replacing a less lucrative pact with HBO.

The Netflix accord, which analysts estimate is worth $30 million per picture to DreamWorks over an unspecified period of years, is billed by the companies as the first time a major Hollywood supplier has chosen Web streaming over pay television.

It is also a bet by Jeffrey Katzenberg, the animation studio’s chief executive, that consumers in the near future will not distinguish between the two. “We are really starting to see a long-term road map of where the industry is headed,” Mr. Katzenberg said in an interview. “This is a game-changing deal.”

Ted Sarandos, Netflix’s chief content officer, added: “You’re seeing power moving back into the hands of content creators. When a company like DreamWorks ends a long-running pay TV deal — when a new buyer in the space steps up — that’s a really interesting landscape shift.”
