SAN FRANCISCO — It took a while, but finally — and with the carefully curated help of Oprah, Big Bird and Goldman Sachs — Apple has at last unveiled a new streaming TV service, its own branded credit card and a news subscription product.

The moves have been largely expected and so far don’ t appear to drastically alter the competitive landscape the way Apple has done with previous products such as the iPhone and the iPad.

Still, the announcements represent an important step for the company as it seeks to diversify how it makes money amid declining sales of the iPhone, even if by themselves they are unlikely to turn Apple’ s big ship either way. But it’ s a way to keep fans sticking with Apple even when they aren’ t buying a new iPhone every year.

Monday’s announcements lacked some key details, such as pricing of the TV service. Here’s a rundown on what Apple unveiled — what’s good, what’ s not so good and what we still don’ t know.

Apple TV Plus

The good: Oprah, Jason Momoa, Big Bird, Steven Spielberg and a host of other stars have lent themselves to original Apple shows that range from documentaries to science fiction, drama and preschool television programming. The focus on “quality storytelling” is consistent with Apple’s image and analysts say is likely to produce some hit shows.

The bad: Even so, “it will lack the full range and diversity of content available through Netflix, Amazon and others, and that is set to limit its appeal,” said Martin Garner, an analyst at CCS Insight. Apple also joins a crowded market and it’s not clear how many more monthly subscriptions people have the money and the bandwidth for.

The unknown: Apple hasn’ t said how much it’s going to cost.

Apple News Plus

The good: The price, $10 per month, looks like a good deal compared to separate subscriptions for newspapers and magazines (Apple will include more than 300 of the latter, including The New Yorker and Sports Illustrated). Apple is touting “richly designed articles” that let people read publications tailored to Apple devices in all their glory. Apple has also included privacy protections, and says it will collect data about what people read in a way that it won’ t know who read what — just how much total time is spent on different articles.

The bad: While The Los Angeles Times and the Wall Street Journal have signed on, other big-name news publishers, such as The New York Times, have not. Nor have, in fact, most other major U.S. newspapers.

The unknown: It’s not entirely clear how much news you’ re getting for your money. The Journal, famous for its business and industry coverage and commanding nearly $40 a month, will make “specially curated” general-interest news available for Apple customers, for example. Other stories will still be there — but Apple says users will have to search for the articles themselves.
