InMobi claims 358% increase in European mobile ad impressions

Yesterday we carried some information from Buzz City about the growth in ad impressions it is seeing in Western Europe.

Now here’s an infographic from InMobi (click for bigger), giving some detail around the impressions it is seeing on its ad network in Europe.

You can see that the number of impressions in Q4 increased just over four and a half times on a year on year basis. It’s also notable that smartphones generated a much greater share of impressions than in 2010, with the smartphone share rocketing from 46% to 83%.

InMobi sees the iPhone 4 and the iPad 1 as its two biggest devices. The Blackberry 8520, which was the second biggest performing device last year, has dropped to third place even though it has increased its share of impressions.

In overall manufacturer terms, Nokia has dropped from a 21.5% share and first place, to a 13.3% share and fourth place. Samsung and Apple have been the chief gainers.

Android OS devices had nearly doubled their share of impressions. Symbian, unsurprisingly, dropped right out of the top three.

In Buzz City’s report, Nokia was still the top performing manufacturer in Italy, with Blackberry far and away the top device vendor driving ad impressions in the UK.
