After AT&T-Time Warner comes the deluge.

Comcast bid $65 billion for Fox's entertainment business on Wednesday, a day after a federal judge has cleared AT&T's $85 billion takeover of Time Warner.

If Comcast succeeds in outbidding Disney for Fox, it would give a major cable distributor control even more channels on its lineup and those of its rivals. There are fears that it could lead to higher cable bills or hinder online alternatives.

But U.S. District Judge Richard Leon cleared the AT&T deal Tuesday despite similar concerns. The ruling signaled that federal regulators might have a hard time stopping companies from getting bigger by gobbling up rivals and the content they own.

Comcast isn't likely the only mega-media bid in the works. There will probably be a rush to consolidate. Cowen analyst Gregory Williams said the ruling could unleash "pent up" demand for mergers and acquisitions "across the Pay-TV landscape."

Even if a company doesn't need to get bigger right away, it might need to do so to prevent being overshadowed by a competitor.

Here's a look at some of the proposed combinations that could transform the media landscape and change how people get their entertainment.

FOX WITH DISNEY OR COMCAST

Disney has made a $52.4 billion all-stock offer for the bulk of Twenty-First Century Fox, including the studios behind the "Avatar" movies, "The Simpsons" and "Modern Family," along with National Geographic. Marvel would get back the characters previously licensed to Fox, reuniting X-Men with the Avengers.

Now Comcast has struck back with a larger $65 billion offer, all in cash. If Comcast succeeds in snapping up Fox, it could diminish the appeal of a planned Disney streaming service, which would heavily feature movies and shows from Marvel and the "Star Wars" franchise.

David Turetsky, a professor at the State University of New York at Albany, warns that the AT&T ruling is based on "specific facts and evidence" that may or may not apply in other cases. Still, there are many similarities between a Comcast-Fox combination and the AT&T-Time Warner deal that just passed judicial muster.

Comcast made its bid after the close of trading, but Wall Street was braced for a bidding war. Shares in Fox increased 7.5 percent to an all-time high of $43.41. Disney gained almost 2 percent, while Comcast edged down six cents to $32.32.

SPRINT AND T-MOBILE

In April, the two telecom companies announced a $26.5 billion combination. The deal would combine the nation's third- and fourth-largest wireless companies and bulk them up to a similar size to Verizon and AT&T, the industry giants.

The worry is that with just three major carriers, there would be less incentive to keep innovating on prices and service. T-Mobile and Sprint might even raise prices now that they don't have to try to poach customers off each other.

A 2014 attempt to combine fell apart amid resistance from the Obama administration. But the industry is different just four years later. Wireless carriers aren't just competing with each other, but also with Comcast and others as the wireless, broadband and video industries converge. AT&T is about to get larger with CNN, HBO and other channels from Time Warner. Beyond combining with each other, T-Mobile and Sprint might need its own content acquisition to compete.

CBS AND VIACOM

CBS has resisted pressure from its controlling shareholder, National Amusements, to merge with Viacom, which also is controlled by National Amusements. The two companies used to be one but separated in 2005.

A combination would reunite CBS's television business with Viacom's production studios, similar to the arrangements now in place at NBC owner Comcast and ABC owner Disney. (On the flip side, the Fox television network and studios would separate under a deal with either Comcast or Disney.)

With Viacom, the $6-a-month CBS All Access streaming service might have a larger library, as Viacom owns MTV, Nickelodeon, Comedy Central and other cable networks.

VERIZON

Verizon, which bought AOL and Yahoo in recent years, could be on the prowl for other entertainment properties. Verizon wants to challenge Google and Facebook in the huge and lucrative field of digital advertising — and having more content could help. There's speculation that CBS could be a potential target. With its main wireless rival AT&T becoming even more of a content powerhouse, Verizon might feel the need to grow.

Cowen's Williams suggests, however, that rather than buy an entertainment or media company, Verizon might buy a company that bolsters its network or infrastructure. Cable company Charter or satellite TV company Dish are "ideal candidates," he wrote in a research note.

SMALLER MOVIE STUDIOS

Rumors have long swirled that Lionsgate might be a potential takeover target by anyone from Amazon to Verizon or even a combined CBS-Viacom entity. Nothing has materialized yet for the owner of the "Twilight" and "Hunger Games" franchises. As a smaller studio, Lionsgate needs to get bigger to compete in the current landscape.

Similarly, Viacom-owned Paramount studio has been on the chopping block before. After years of troubles, it has recently rebounded with the horror film "A Quiet Place" and comedy "Book Club." That could make it a lucrative takeover target by a company seeking content creators.
