Mobile "drives so much traffic" because many people start their day reading news on a phone or tablet, said Cindy Krum, chief executive at MobileMoxie, a mobile marketing consultancy.
Several new apps hope to capitalize on that by attracting news readers and the advertising dollars they bring.
Apple News, an app included in Apple's updated iOS 9 mobile operating system, launched last month, delivers content from more than 50 media partners, including the New York Times, Vanity Fair and Vogue.
Facebook launched its "Instant Articles" earlier this year in partnership with a number of media organizations to provide access to the news 10 times more quickly, through its social media infrastructure, than most news websites do.
And Google is said to be preparing a similar system in partnership with Twitter to allow mobile users to fully load an article on their phone in a fraction of a second, compared with nearly 10 seconds today.
The rapid development of the news products demonstrates how mobile has become the new battleground for tech companies seeking to keep users within their ecosystems, where they can reach them with more products, services and advertising.
"There's a big competition for mind share," Americans spend an average of three hours per day on mobile devices, compared to just over two hours on PCs, according to the research firm eMarketer.
Mobile advertising is surging. North American mobile ad spending is set to jump to $61 billion (roughly Rs. 3,98,297 crores) by 2018 from $19.7 billion (roughly Rs. 1,28,630 crores) last year, according to eMarketer.
A new model?
The moves are giving media companies incentives to make their products more mobile friendly.
The New York Times will allow access to 30 free articles per day on Apple News, for instance, compared with 10 per day for readers who go to the daily's website or news application.
But it remains unclear whether these new apps will help news organizations find a lasting economic model to survive the digital age.
According to the Pew Research Center, daily US print circulation is down 19 percent over the past decade and print advertising has fallen more than 60 percent.
In combating that decline, news organizations have to decide whether to go after digital readers on their own or to team up with tech firms.
In these new apps, the publishers appear to have chosen the latter.
"For now, the agreements look pretty favourable to the publishers," said Rick Edmonds, media business analyst for the Poynter Institute for Media Studies.
But Edmonds said the long-term impacts remain unclear, especially as to how the partnerships will affect the digital subscriptions or purchases of individual articles previously sold directly by the media outlets.
"It's an open question," Edmonds said.
A New York Times spokesman said it is "important to ensure that The Times is available in a wide variety of places where people find their news and information," noting that the daily can be accessed through services such as Flipboard, Microsoft's MSN News, or Google Play Newsstand.
Krum agrees, saying news organizations need to adapt to the ways consumers access the news today.
"It's much more casual" than in the past, she said. "It's not like going to buy a newspaper any more. The newspaper has to find you."
