Admob has published the first sliver of real evidence that Iphone usage is slipping due to the onslaught of Android powered devices.Admob was courted by Apple prior to a $750 million buyout by Google. Insurance For Day . The firm was seen by both as a vital tool for bolstering their revenues from the ever growing number of mobile subscribers.The firm released detailed figures for which handsets it served ads to and it makes for bittersweet reading for both Apple and Google. The bigger picture showed that almost 50 per cent of all ads served by the firm were to smartphones. Denver Web Design . Feature phones, the phones that punters plump for when they can’t afford a real smartphone, continue their sharp decline with Admod serving around 35 per cent of its ads to such devices.That in itself isn’t bad news as smartphones represent a bigger canvas for advertisers, however the lack of Flash support on Apple’s Iphone must be limiting the flow of creative juices of artsy media types everywhere.The Iphone holds a commanding lead when it comes to ad display share, as 50 per cent of all ads served were to Iphones, a growth of 17 per cent since February 2009. For Steve Jobs that figure must sound stellar until he reads that it was eclipsed by Android devices, which saw a 22 per cent growth, coming in just shy of 25 per cent. Further bad news lies beneath the headline figures for Jobs.Admob was able to track, with great detail, what devices displayed its ads, and when looking at monthly breakdowns the Iphone is losing ad market share hand over fist. In the US, the Iphone was down 0.9 per cent from January 2010 and that figure was 5.9 per cent in the UK. Worryingly for Jobs’ Mob the Iphone’s drop in share was the highest of any device in Admob’s top 10. Even smartphone suicide artists, Palm managed to post better, albeit negative, growth figures.The biggest gainers in the US were Motorola’s Droid, Samsung’s Moment and HTC’s Magic, all Android devices. Aside from a very impressive showing from Nokia’s N73 here in the UK, individual Android devices posted very favourable results in the West.Going further east, Nokia fills the tables in India, Indonesia and South Africa. However Symbian suffered a terrible year, with Admob’s figures showing a stunning fall from grace for the much maligned mobile operating systems. After starting 2009 as the most popular platform for ads with 43 per cent, by February 2010 that figure was whittled down to just 18 per cent.The fruity toymaker simply cannot ignore Android anymore, with further research carried out by Admob showing that more than 70 per cent of Iphone developers plan to code Android apps. However less than half of all Android developers can be bothered to bend over and accept Steve Jobs’ unswerving development and deployment practices.Advertising is playing an increasing role in funding developers as respondents said that almost 80 per cent of their revenues came from adverts. However considering the figures are being published by a firm peddling advertising, that’s hardly surprising. Nevertheless, given that the average cost of apps hover around the $2 mark, it’s evident that developers have to recoup their outlay in other ways and advertising is a simple and well tested way to do that.Given the over the top demands that Apple places on its developers, it’s hardly surprising that five per cent of those who answered said that they were “very dissatisfied” with the Iphone. Only Symbian topped that, but considering that Symbian has all but fallen off a cliff in the past three years one wonders how many developers see their future in coding apps for old Nokia devices.Unlike most fanbois who are struck by pretty graphics and colourful fascias, developers typically look beyond the glitz and see the underlying functionality. Perhaps that is the reason why the Iphone has a mere one per cent lead over Android when it comes to market share among developers themselves. Clearly many developers would have both devices in order to effectively demo their apps before sending them to Apple’s censors, but given that currently more develop for the Iphone than for Android, it seems that personal, not professional choices push them towards Android.These figures don’t spell the end of the Iphone but they do tend to suggest that punters are recognising credible alternatives, namely Android. If the availability of apps is the primary driver for a smartphone system succeeding then the one that rakes in the most cash for developers is more likely to last the distance.For Jobs’ Mob the honeymoon is well and truly over. deurveer . Iphone growth has stagnated and in a few markets reversed at an alarming rate. Clearly at some point the cut down smartphone’s appeal would plateau, however with the sheer number of Android devices appearing, the cappuccino firm is seemingly unable to hold out against the army of technologically superior devices.Going down into the nitty gritty of Admob’s figures, Android handsets are eating into the Iphone’s main method of revenue generation for developers. The good news for them is that they are able to take advantage of Android’s openness and freedom to produce apps, which not only generates more cash but also promotes Google’s open source smartphone OS.
