A federal judge approved the $85 billion mega-merger of AT&T and Time Warner on Tuesday, a move that could usher in a wave of media consolidation while shaping how much consumers pay for streaming TV and movies.

U.S. District Judge Richard Leon green-lit the merger without adding major conditions to the deal. The Trump Justice Department had sued to block the $85 billion merger, arguing that it would hurt competition in cable and satellite TV and jack up costs to consumers for streaming TV and movies.

Now, the phone and pay-TV giant will be allowed to absorb the owner of CNN, HBO, the Warner Bros. movie studio, "Game of Thrones," coveted sports programming and other "must-see" shows. The Justice Department could decide to appeal the ruling, however.

"The impact from this decision will have wide-reaching ramifications across the telecommunications, media and tech industry for decades to come," said GBH Insights analyst Dan Ives. "For AT&T and Time Warner, this is a major victory lap."

The mega-merger was a high-stakes bet by AT&T on combining a company that produces news and entertainment with one that funnels it to consumers.

The merged company, executives said, would be better able to compete in an era in which people spend more time watching video on phones and tablets and less time on traditional live TV on a big screen.

Leon said the government failed to prove that the merger would lead to higher prices and other harm for consumers.

"The government here has taken its best shot to oppose this merger," Leon said, speaking to a packed courtroom in an unusual session weeks after the trial ended. But, he added, "the government's evidence is too thin a reed for this court to rely on."

Leon rejected the notion of temporarily suspending the merger for a possible appeal by the government. The "drop dead" deadline for completing the merger is June 21. If it's not wrapped up by then, either company could walk away, and AT&T would have to pay a $500 million breakup fee.

The ruling is a stinging defeat for the Justice Department. The proposed merger was so big and consequential that it forced federal antitrust lawyers to reconsider legal doctrine that permitted mergers of companies that don't directly compete. First floated in October 2016, the deal also brought fire from then-candidate Donald Trump, who promised to kill it "because it's too much concentration of power in the hands of too few."

Dallas-based AT&T is a wireless, broadband and satellite behemoth that also became the country's biggest pay-TV provider with its purchase of DirecTV. It claims about 25 million of the 90 million or so U.S. households that are pay-TV customers.

Leon's ruling could shape the government's future competition policy.
