Ad impressions reached a record high during the fourth quarter of 2012, according to data from Opera’s latest State of Mobile Advertising report, with revenue to publishers more than twice that of any previous quarter throughout the year.

Apple and Samsung are the only two smartphone manufacturers currently seeing any growth in the United States. The pair are slowly eating away at the market share held by their rivals, including LG, Motorola, Research in Motion, and HTC.

Combined they populate 82% of the smartphone market, up 27.6% since Q1 2011. These numbers are an amazing testament to Android’s growth as well as iOS’s stability (which is amazing considering they only have a few devices).
