Google smartphone Nexus One was launched as an additional platform for the company's mobile marketing tools, an IT expert has claimed.
James Atkinson, editor of Mobile, has said that Google's "end-game" when launching any future smartphone is to increase their mobile advertising.
"For Google it's never going to be about the phone itself. It's all about getting you to look at more ads," he said.
"All they want to do is boost their ad revenues, and that's the end-game for them, rather than being a real competitor in the handset market."
However, Mr Atkinson did not say that this was necessarily a bad prospect for the company.
He said that Google, in the same way as Apple, could "suddenly change direction" and launch a real contender to the iPhone.
"You wouldn't want to bet against Google trying to do something like that," he warned.
Although the Nexus One had initial poor sales on its launch, IT stock analysis service Trefis has estimated that five million handsets will be sold this year.
