NEW YORK ( TheStreet) -- More than 24 million people are expected to buy tablets this year, and this figure will grow to 35 million in 2012, according to a new report from Forrester. New versions of Apple's ( AAPL) iPad, as well as the next generation of Google's ( GOOG) Android platform will help boost tablet sales, the report said.

Shares of Apple fell 0.44% in pre-market trading Wednesday to $329.96 while shares of Google were down 0.27% to $600.50.

Mozilla's Firefox has unseated Microsoft's ( MSFT) Internet Explorer as the leading web browser in Europe, according to a new report from Irish research company StatCounter. This is the first time in a decade that Internet Explorer is not the top browser in the European market.

Shares of Microsoft fell 0.24% in pre-market trading to $28.02.

Amazon ( AMZN) has opened its Android store for developers to submit applications when the store officially launches later this year. While developers will be able to suggest a list price for their apps, Amazon will set the actual price, which differs from both the Apple and Android app stores.

Shares of Amazon were down 0.33% in pre-market trading to $184.40.

The amount that marketers will spend on advertising on mobile gaming platforms will increase ten-fold over the next five years, according to a report from Juniper Research. Advertising spend will reach $894 million by 2015, up from $87 million in 2010.

Turn, an online advertising technology startup, has raised $20 million in new funding. The Redwood City, Calif. company has raised $57 million in total funding from investors including Greenberg Associates, Norwest Venture Partners, Trident Capital, Shasta Ventures and Focus Ventures.
