NEW YORK (Reuters) - Rupert Murdoch looks to have been canny in his $80 billion (46.81 billion pounds) takeover approach to Time Warner Inc (>> Time Warner Inc), cornering the media giant at a time when potential "white knight" bidders are busy absorbing their own large deals.

The absence of potential counter-bidders leaves Time Warner's investors with a dilemma. They can either engage with Murdoch's Twenty-First Century Fox Inc (>> Twenty-First Century Fox Inc) to negotiate a higher price, or play for time and wait until there are more potential buyers available.

Time Warner, owner of many highly-prized assets from HBO to Warner Bros, has rejected Fox's initial cash-and-stock proposal of $85 per share. An eventual deal would transform the U.S. media landscape and cement Murdoch's status as the most powerful magnate in U.S. media and entertainment.

When Time Warner's board rebuffed the approach it indicated it believes now is the wrong time to sell because the environment isn't conducive to getting the best price, people familiar with Time Warner's thinking said on Wednesday. That is mainly because a range of major media, telecom and technology companies are for various reasons not in a position to make a rival offer.

Verizon Communications Inc (>> Verizon Communications Inc.), which last year paid $130 billion to buy Vodafone out of its U.S. wireless business Verizon Wireless, is hampered by the $140 billion debt load that it took on as a result.

Comcast Corp (>> Comcast Corporation), which completed the acquisition of NBC Universal last year, has its hands tied while waiting for the government to approve its proposed $45 billion takeover of Time Warner Cable (>> Time Warner Cable Inc). Bidding for Time Warner while that is going on could scuttle the chances of getting the cable deal approved.

Elsewhere, AT&T Inc (>> AT&T Inc.), another large telecom company that hardly produces any programming, is trying to close its $48.5 billion takeover of satellite TV company DirecTV (>> DIRECTV), which is also awaiting regulatory approval.

As the media industry landscape evolves, technology companies such as Google, Apple or Amazon could also be tempted into bidding for Time Warner as opposed to trying to produce video content on their own, people familiar with Time Warner's thinking said.

Time Warner shareholder Mario Gabelli told Reuters Insider TV on Wednesday that he thought both Google and Apple were possible bidders.

But for now, Google's investment in content is focussed on its YouTube unit while Amazon has spent money on original TV shows for its online video service. Apple's media bets have so far been on music, illustrated by its purchase of Beats Music in May for $3 billion.

"If I were Time Warner, I would wait. A year or two from now, they will have competition for the assets actually," said an industry banker who is not involved either with Time Warner or Fox.

"The only downside of waiting is if you believe that multiples are going to contract in the next year or two. Nobody assumes that the markets are going down," the banker said.

For Fox, stars seem to be aligned for a deal. Financing remains cheap, making it easy for Fox to borrow the cash it will need for the deal. Its stock, which Fox wants to use to finance 60 percent of its bid, is trading at a lofty multiple to earnings.

"In our experience, if Mr. Rupert Murdoch wants an asset, he

will wait and pay to get it," ISI analyst Vijay Jayant said.

UNINTENDED CONSEQUENCE

Still, Time Warner shareholders have told Reuters that Murdoch will have to raise his bid and increase the cash component to stand a chance of succeeding.

Also companies don't always get to choose the place and time of a battle. Fox's overture could force another company to think hard about making a competing bid, and Murdoch could get trumped.

Investors in cable and media have seen this movie before. Earlier this year, Charter Communications (>> Charter Communications, Inc.) went public in its pursuit of Time Warner Cable and ended up losing out to Comcast, which swooped in as a white knight with a surprise offer of its own in February.

People familiar with Comcast told Reuters at that time that while it had historically been intrigued by the idea of buying Time Warner Cable, such a deal was not high on its priority list until Charter started pursuing the company.

"By going public you could run into the unintended consequence that other people start to think it's important for them and they go after it," said a second industry banker.
