Google had a big month: a new version of Google Groups, a search engine for open source code, Writely and Google Spreadsheets joining forces, better charts in Google Finance, a custom search engine, a new and better Froogle.

Google bought YouTube to improve its presence in the online video space and JotSpot, a wiki company that develops products similar to Google Docs & Spreadsheets and might improve the integration of other tools.

Google surprised everyone with SearchMash, a new interface for Google Search, and decided to restructure its products.

October is also the month when Google Operating System celebrates one year online. </img> </img> </img> </img>
