SAN FRANCISCO (AP) — Netflix’s fourth-quarter earnings soared six-fold as the Internet video service added another 2.3 million U.S. subscribers to burnish its status as one of the world’s most popular entertainment outlets.

The financial results announced Wednesday topped analyst estimates, and Netflix basked in Wall Street’s adulation. The company’s stock surged $58.57, or more than 17 percent, to $392.30 in extended trading.
