The Copley Press announced Thursday that it's putting The San Diego Union-Tribune up for sale. "The last couple of years have been a difficult period for the newspaper industry, especially those in a real estate-dependent market like San Diego," says Copley executive Harold W. Fuson Jr. "The uncertainties pose too great a risk to sit still." Copley has retained New York-based investment firm Evercore Partners to "explore strategic options, including a potential sale." Copley sold its other properties in California and the Midwest in 2006 and 2007.

With a duopoly in satellite radio getting regulatory approval, Wall Street is pondering if the next development will be a satellite-TV duopoly of Dish Network and DirecTV. Sanford C. Bernstein analyst Craig Moffett doesn't think so. "A DTV/DISH merger is not any more feasible in Washington than before, because the regulatory issues ... are entirely different" from satellite radio, he says. Moffett says XM-Sirius is perceived to be part of a large market that includes terrestrial radio and portable music devices. It's also highly competitive. But satellite TV is a monopoly in rural America, where fixed-wire cable service …

Antony Young, president of Optimedia, studies which superhero movie packed the biggest media punch. The marketing behind both the Hollywood franchises was a critical ingredient in their box office success, but they each took very different media strategies. Batman wins, barely. Young concludes that "The Dark Knight" displayed innovation, particularly on the Web, and was "much savvier in its PR efforts." The unexpected death of Heath Ledger also significantly boosted awareness of the film, and was handled gracefully. "Iron Man," on the other hand, did "amazing" things with a smaller budget, using promotions particularly well.

As the newspaper industry is being knocked back on its heels, the New York Times Co. Wednesday reported an 11% drop in second-quarter advertising revenue and an 82% plunge in quarterly earnings compared with a year ago, when the bottom line was boosted by the sale of a broadcast unit. The outlook for the current quarter is no better. Advertising revenue fell 18% in June, and there has been no improvement so far in July, says CEO Janet Robinson. Advertisers "are really saving dollars" to offset higher energy costs and lower consumer spending. "The economy has gotten …

LinkedIn members reading an article in the business or technology sections of NYTimes.com will now see a box featuring five Times newspaper stories selected for them based on their LinkedIn profile. They will also see ads based on that profile. Business and technology were considered the optimal sections in which to use the targeted-news and ad feature because members of the LinkedIn social network are mostly professionals. Denise Warren, NYT ad executive, calls it "a groundbreaking relationship...that both companies decided to try in a limited way at first." She says the paper has no immediate plans to …

World Wrestling Entertainment plans to produce its three weekly TV series in a way that lands them a PG rating. WWE says it will focus more on its over-the-top characters and storylines, rather than the attention-grabbing stunts that sometimes have been considered too outrageous in the past. Its film division, WWE Studios, will also steer away from R-rated content. The moves are part of the company's new effort to appeal to younger audiences and families. WWE recently launched a kids magazine and a youth-oriented Web site with original content. "It's the continuing evolution of the company to …

The lawsuit comes two months after the TV networks wrote to the privately held site asking it to stop running unauthorized clips and programs.
