Tina Brown, one of New York's best-established British media figures, has set her sights on Newsweek, the historic but ailing weekly news magazine, in a move that could intensify her rivalry with Arianna Huffington, proprietor of internet magazine the Huffington Post. 
 
 Brown's ambition for the project is not in doubt – she has confirmed rumours of discussions between billionaire Barry Diller, the backer for her own online publication, the Daily Beast, and Newsweek's nonagenarian proprietor, Sidney Harman. But the New York media establishment is perplexed: why would Brown – a veteran of print magazines including Tatler, Vanity Fair, The New Yorker and her own ill-fated venture, Talk – or Diller want another money-losing proposition? 
 
 Newsweek, which lost $30m (£19m) last year, has suffered an exodus of editors and reporters since it was bought recently by Harman for $1; the Daily Beast, into which Diller's IAC group pumped as much as $20m, has no apparent business plan beyond his deep pockets. For Diller, merging Brown's Daily Beast with Newsweek would get the Beast off his books and, in a stock deal, give Diller a significant stake in Newsweek to add to his disparate media holdings. 
 
 "It could end up being a smart deal for Barry and Tina," said media commentator Michael Wolff. "It allows Barry to monetise the Daily Beast and gives Tina a vastly expanded platform." 
 
 Literary agent David Kuhn, a former associate of Brown's, told Chris Rovzar's Daily Intel blog on New York magazine's website that he welcomed the idea of a Brown-directed Newsweek. "Even a slimmed down Newsweek – in terms of staff and budget – will give her more to work with than she's working with at the Beast, or at Talk, so I'd say she has a better shot than most anyone at making the magazine work, or work for a while." 
 
 Others fail to see the point. "It doesn't seem like a solution," said an editor at another online operation, Slate.com. "It's the acquisition of two problems instead of one." 
 
 Within the Manhattan media orbit, Brown's moves are largely viewed in the context of her rivalry with Huffington. Brown, who is known for her competitiveness, is now locked in a battle with Huffington for staff and traffic. And it's personal. "They simply cannot stand each other," said one media executive familiar with both women. "Arianna's rise is deeply wounding to Tina, and the raison d'etre of the Daily Beast is to try to catch Arianna." The feeling is apparently mutual: "Tina, in her heyday, didn't give Arianna the time of day. There's a certain amount of schadenfreude here." 
 
 This week, Brown hired the veteran Washington Post media writer Howard Kurtz – "I don't think you're going to be seeing Daily Beast hiring 20 reporters of that calibre," said one senior executive – while Huffington hired Newsweek's chief political reporter Howard Fineman. 
 
 Huffington Post executives tend to dismiss the Daily Beast's challenge and describe their rival's traffic as "negligible". They note their site's internal count of traffic, in terms of unique visitors, is almost as high as the New York Times at 45 million. 
 
 The Huffington Post is projecting profitability this year on revenues of $30m, with revenue rising to $60m in 2011-2012. "We're growing for three reasons," said the company's chairman, Kenneth Lerer: "Content, technology and community." One measure of "community" – user comments – is up to 3m a month. 
 
 For Brown, who has a reputation for showing scant regard for her employers' money, the prospect of a Beast-Newsweek deal comes with an implicit threat – that Diller will not stand for years of losses. 
 
 "The most interesting thing about [a Newsweek-Beast deal] is that it suggests Diller is not endlessly patient," British online mogul Nick Denton, founder of Gawker, told Rovzar this week. "I thought he would give Tina more time and money."

 Talks between news-and-commentary website the Daily Beast and Newsweek have fallen through, according to a report in The Wall Street Journal that was confirmed today by a memo from Beast editor Tina Brown to staff. There had been much buzz in recent weeks about a potential merger between the growing site and the struggling magazine, which was recently unloaded by the Washington Post Company. The potential deal would have seen Brown assume editorial control of the magazine, but an agreement couldn't be reached on how Brown, new Newsweek owner Sidney Harman, and Beast backer Barry Diller would share control. "The engagement was fun but the pre-nup got too complex," wrote Brown in a memo to her staff today, obtained by Intel. "We wish Newsweek all the best." 
 
 Daily Beast Drops Out of Talks With Newsweek [WSJ]
– Sure, the Daily Beast's Tina Brown wants a Newsweek merger because she crazy-hates rival Arianna Huffington, or so claims the Guardian. "We are sooooo busted," laments one AriHuff in a "leaked" IM conversation with one TBrown. "How did they find out we 'simply cannot stand each other?' I thought we’d done such a good job hiding it over the past four decades," AriHuff rejoins in the new media mavens' takedown of the old media. "I truly thought we’d pulled the wool over their eyes when I agreed to contribute to the Daily Beast when it launched,"AriHuff continued, wondering if they "would ever run a piece about two guys’ business strategy being fueled solely by bitch-slap rivalry?" Brown responds: "The male editors around town all must be bosom buddies, because otherwise the Guardian’s crack investigative team would no doubt have exposed them." Ironically, both sites are attracting a growing number of journalists defecting from print media, a Politico profile notes.
