Despite a variety of new smartphone launches in the US from various manufacturers, there has been remarkably little change in market share.

According to research company comScore, taking the three-month average until end-October, Apple was the leading smartphone manufacturer in the country with a 40.3 per cent share, up a slender 0.2 percentage points on the previous three-month average ended July.

The Cupertino giant may well be disappointed that a spike in October sales, through the first full-month availability of new iPhone models 5S and 5C, did not make a greater impact on the latest three-month average.

Market share of second-placed Samsung grew by a modest 1.3 percentage points, over the same period, to 25.4 per cent.

HTC, LG and Motorola remain tightly bunched together with market shares hovering around 7 per cent.

Little change, too, was found in the smartphone OS space.

Android ranked as the top smartphone platform by October with a 52.2 per cent market share (up a thin 0.4 percentage points compared with the previous three-month average), followed by Apple with 40.6 per cent (up 0.2 percentage points), BlackBerry with 3.6 per cent (down 0.7 percentage points), Microsoft with 3.2 per cent (up 0.2 percentage points) and Symbian with 0.2 per cent.

Google Sites ranked as the top web property on smartphones, reaching 88 per cent of the mobile media audience, followed by Facebook (84.4 percent), Yahoo Sites (77.9 per cent) and Amazon Sites (65.3 per cent).

Facebook ranked as the top smartphone app, reaching 75.7 per cent of the app audience, followed by Google Play (54 per cent), Google Search (52.2 per cent) and Pandora (48.2 per cent).
