LOS ANGELES, April 18 (Reuters) - Netflix blew past Wall Street expectations for the second straight quarter on Thursday as ad-supported streaming plans helped bring in 9.3 million new customers, nearly double the consensus forecast of analysts.

Earnings per share for January through March came in at $5.28, compared with $2.88 a year earlier.

Netflix revenue rose 14.8% to nearly $9.4 billion during the period, when the service debuted titles such as sci-fi drama series "3 Body Problem" and crime thriller "Griselda."

Operating income totaled $2.6 billion, a year-over-year increase of 54%.

Analysts had expected Netflix to gain roughly 5 million subscribers around the world during the quarter, according to LSEG data, after record gains at the end of 2023.

The additions brought Netflix's total subscribers to 269.6 million at the end of March.

"We have built a hard to replicate combination of a strong slate, superior recommendations, broad reach and intense fandom, which drives healthy engagement on Netflix," the company said in a letter to shareholders.

As competitors such as Walt Disney are losing money from their streaming efforts, Netflix keeps gaining customers and building profit. In the shareholder letter, the company said it would work to improve the variety and quality of its entertainment and scale its advertising business to grow further.

Netflix began offering ad-supported plans, which cost less than half of the options without commercials, in November 2022. In 2023, it started a crackdown on sharing of passwords, trying to convert people who use the accounts of friends or family into paying subscribers. The company said the version of its service with ads now accounts for 40% of all sign-ups in markets where it offers the plan. To satisfy its large global audience, Netflix has been broadening its programming. The streaming service is expanding its sports offering with a $5 billion, 10-year deal to stream WWE's wrestling show, "Raw," starting in January 2025.

The company recently restructured its film division under new leader Dan Lin and is aiming to produce fewer, higher- quality movies for streaming. (Reporting by Lisa Richwine and Dawn Chmielewski in Los Angeles Editing by Matthew Lewis)
