What is important to observe is not the share numbers in the link above but the absolute growth and trend.
Doing a bit of algebra from the data Admob provided we can calculate that:
- The overall traffic admob handled was 14.1b up from 6.6b a year ago. (114% growth)
- Smartphones generated 6.78b impressions in February, up from 2.3b a year ago. (193% growth). The iPhone OS generated 3.4b impressions.
- Feature phones generated 4.9b, up from 3.5b (43% growth)
Although it’s dangerous to equate “usage” to these impression numbers, the overall trend is that most of the growth is happening on smartphones. Of those, the iPhone OS and Android are taking 75% share of eyeballs, at least on Admob’s network.
The iPhone platform generated as many impressions in February as all feature phones generated a year ago. It does not seem a stretch to predict that iPhone will overtake all feature phones in overall impressions in the near future.
