The deal, which has been agreed on most terms and could be announced as early as Sunday, would be one of the largest in recent years in the sector as telecommunications companies look to combine content and distribution to capture customers replacing traditional pay-TV packages with more streamlined offerings and online delivery.

AT&T, which sells wireless phone and broadband services, has already made moves to turn itself into a media powerhouse, buying satellite TV provider DirecTV last year for $48.5 billion.

It also in 2014 entered a joint venture, Otter Media, with the Chernin Group to invest in media businesses, and has rolled out video streaming services.

AT&T will pay $110 per Time Warner share, or about $85 billion overall, sources told Reuters. That would make it the biggest deal in the world this year.

Time Warner’s shares (TWC) rose almost 8% in regular trading, and a further 4.7% after hours, to $93.84, giving it a market value of about $73 billion. AT&T (T)finished down 3% at $37.49.

Time Warner is a major force in movies, TV and other areas, with HBO, CNN, Cartoon Network, TBS, TNT, TruTV, Turner Classic Movies, the CW network, New Line Cinema, DC Comics, Castle Rock Entertainment and other assets. Time Warner disclosed a 10% stake in video streaming site Hulu in August.

Time Warner Chief Executive Jeff Bewkes rejected an $80 billion offer from Twenty-First Century Fox in 2014, but sources said on Friday that the former suitor had no plans to renew its bid.

The Wall Street Journal reported on Friday that Apple Inc approached Time Warner a few months ago about a possible merger and has been monitoring its talks with AT&T.

An agreement between Dallas-based AT&T and New York-based Time Warner could be announced as early as on Monday, according to the sources, who asked not to be named because the talks are confidential.

CONTENT AND DISTRIBUTION

Owning more content gives cable and telecom companies bargaining leverage with other content companies as customers demand smaller, hand-picked cable offerings or switch to watching online. And new mobile technology including next-generation 5G networks could make a content tie-up especially attractive for wireless providers.

“We think 5G mobile is coming, we think 5G mobile is an epic game-changer,” Rich Tullo, director of research at Albert Fried & Company, said in a note, adding that mobile providers would be in position to disrupt traditional pay-TV services.

The Wall Street Journal reported earlier on Friday that AT&T and Time Warner were engaged in advanced talks and a cash-and-stock deal could come as soon as this weekend.

A previous Time Warner blockbuster deal, its 2000 merger with AOL, is now considered one of the most ill-advised corporate marriages on record.

Time Warner was not immediately available for comment. AT&T declined to comment.

Cowen and Co analyst Doug Creutz, who said AT&T would need to pay at least $100 a share in mostly cash to acquire Time Warner, questioned the strategy of buying content instead of licensing it.

“What does it get them that they can’t get by licensing Time Warner content and at a much cheaper price than buying the whole company?” Creutz asked, noting it was unclear what savings could be gained “from stapling distribution and content together. It’s been tried. It never works.”

AT&T would likely be able to win U.S. antitrust approval for the deal, some experts said, but it is unclear whether certain conditions would be needed to win that approval.

The U.S. Justice Department “will look at it but they won’t stop it,” said Darren Bush, who teaches antitrust issues at the University of Houston. Bush predicted regulators as a matter of course would make a second request for information, meaning the review would last several months.

Andre Barlow, an antitrust lawyer at the law firm Doyle, Barlow and Mazard, noted that the government may worry about whether other cable and internet companies would continue to have access to Time Warner content like HBO and CNN.

The media industry has been seen as ripe for consolidation, and several stocks rose on the news, including Netflix, which closed up about 3.4%, and Discovery Communications, which ended up 3.6%.
