Mobile ads to push Twitter ad revenue near $1 billion in 2014: report




(Reuters) - Twitter will generate nearly $1 billion in ad revenue next year due to a surge in mobilea dvertising on its Web microblogging service, according to a report released on Wednesday.



Mobile ads will account for roughly half of Twitter's advertising revenue this year and will make up more than 60 percent of the company's ad revenue by 2015 according to research firm eMarketer.



The increasing popularity of Twitter's mobile ads - introduced in March 2012 - caused eMarketer to raise its 2014 ad revenue estimates for Twitter to $950 million, versus its previous estimate of roughly $800 million. Twitters' ad revenue this year will total $582.8 million, according to the report, roughly double what it was in 2012.

Twitter, which allows people to share 140-character messages on its online service, is privately held and does not disclose financial results.

With more than 200 million monthly active users, Twitter is among the Web's most popular social networking services, along with Facebook Inc, and is expected by analysts to float shares to the public within two years.

As consumers increasingly access the Web on smartphones, mobile ads have become increasingly important to the businesses of Web companies such as Facebook and Google Inc. Facebook said in January that its mobile ad revenue doubled from the third quarter to the fourth quarter, representing roughly 23 percent of its $1.33 billion in fourth-quarter ad revenue.

"Twitter has ultimately benefited from the increased focus on mobile by competitors like Googleand Facebook, which have both expanded their own mobile ad offerings and worked to convince advertisers to shift dollars to mobile devices," eMarketer said on Wednesday.

eMarketer said its revenue forecasts are based on analysis of reports that track media buying trends, Twitter usage data and interviews with executives at advertising agencies, online publishers and others.

Samsung Galaxy S4 vs. Nexus 4

Nexus and Galaxy. The two brands represent opposing ends of the Android spectrum. Nexus devices have always been Google’s pure, untarnished vision of its platform. Samsung’s wildly-successful Galaxy devices, meanwhile, still use Android, but also threaten to overshadow it. What happens when you put the best of each side-by-side? Read on, as we compare the specs and features of the Samsung Galaxy S4 and LG Nexus 4

Size

 The Nexus 4 is a bit shorter, narrower, and thicker. But – when you look at smaller rivals like the iPhone 5, or phablets like the Galaxy Note II – you realize that the size differences here are pretty minor.

Build

It’s easy to poo-poo on Samsung’s use of plastic, but you could also argue that it allows the company to focus more of its expenses on things like 1080p displays and octa-core processors.
The front and back of the Nexus 4, meanwhile, are made of Gorilla Glass. LG helpfully placed a rubbery band around the phone’s edges, allowing for an easier and more comfortable grip.
That extra grip is a good thing, considering that – no matter how strong Gorilla Glass is – it’s going to be more prone than plastic to cracks and scratches.
Both sets of materials have their pros and cons, and this is probably one of the first big areas you’ll want to think about when deciding between these two handsets.

Weight





It’s impressive that LG managed to make the glass Nexus 4 only 9 g (0.32 oz.) heavier than the plastic Galaxy S4. We suspect the GS4’s larger battery (see below) has something to do with that.

Display


The Galaxy S4’s display is both larger and sharper than the Nexus 4’s screen.
Once you get to a certain level of sharpness (probably around 300 pixels per inch), cramming in more pixels ceases to play as big of a part. Both of these screens are razor sharp, and your eyes won’t likely see any individual pixels on either one.
That means the display technology will play a bigger part. The Galaxy S4’s Super AMOLED has blacker blacks (technically no light comes through black pixels) but hyper-saturated colors. The Nexus 4’s IPS display, meanwhile, leads to better viewing angles and more accurate color reproduction.

Processor




The Nexus 4’s Snapdragon S4 Pro chip is a beast. Ditto for both versions of the Galaxy S4: the North American version’s quad core Snapdragon 600 and the international version’s octa core Exynos chip.
In terms of benchmarks, the Galaxy S4 is going to beat the Nexus 4. In terms of experience, though, you probably won’t see much of a difference. All three processors should blaze through just about any app you throw at them.

RAM

 Our two entrants are tied up, each with 2 GB of RAM.

Storage

This is a big-time advantage for the Galaxy S4. The 8 GB offered for the entry-level Nexus 4 isn’t a lot. Add to that the Nexus 4’s lack of an SD card slot, and you could find yourself cramped for free space.
Fortunately, the 16 GB edition of the Nexus 4 only costs US$50 more than the 8GB version.
There’s also the matter of off-contract pricing. Namely, the Nexus 4 was built for it, and the Galaxy S4 wasn’t. Carriers haven’t yet announced pricing for the GS4, but you can bank on around US$200 or so on-contract. The Nexus 4 starts at $300 off-contract.

Wireless

 
Here’s another tough call, as there’s no LTE for the Nexus 4. It does support HPSA+, which offers faster than 3G speeds ... but LTE it is not. You’ll also need to sign up with a GSM carrier for the Nexus 4, as CDMA (that's Verizon and Sprint in the U.S.) networks aren’t supported.

Cameras

 

Megapixels make for an easy-to-read metric for these graphics, but they make for a far-from-perfect representation of camera quality. We’ve yet to put the Galaxy S4 through the paces, but you don’t have to worry about the Nexus 4’s shooter. It takes great shots, and can easily replace a point-and-shoot.

Battery

 

Here’s another stat that isn’t an absolute indicator of experience, as many other factors determine actual battery life.
The Nexus 4 offers solid battery life: under typical use, it will easily last a full day. Does that mean the Galaxy S4 – with more capacity – will get better uptime? Maybe, maybe not. When you consider that it has LTE and a display with over a million extra pixels, it may need that extra capacity to match the Nexus 4’s uptime.

Software

 

One of the most surprising things about the Galaxy S4 is that it will ship with the latest version of Android, 4.2.2.
But you’d be forgiven for thinking the Galaxy S4 runs its own operating system. Samsung is increasingly hiding its Android roots under a heavy layer of “TouchWiz” – complete with a bevy of crazy features (facial-recogntion scrolling, fitness tracking, photos with accompanying audio clips ...).
Meanwhile, the Nexus 4 – like all Nexus devices – runs “pure Google,” or stock Android. What you see is exactly what Android’s creators and designers intended - and nothing more.
Though the two phones run the same version of Android right now, that may not last long. Without manufacturer skins or carrier crapware, the Nexus 4 will be first to receive future Android updates. Samsung has improved its support for updates, but GS4 owners will have to wait much longer for Key Lime Pie (or whatever the next major version is called) than Nexus 4 owners will.
