Google uses a clever way to promote some of its tools that let you find the latest information about the Beijing 2008 Olympic Games. The homepage doodle links to
a search that triggers a special OneBox for medal count.

Google's OneBox includes a link to
an iGoogle gadget that shows schedules, results, and medal counts. There's also
a Google News section for the Summer Games.
Other searches that trigger Google OneBoxes: sport, olympic sport (e.g.:
olympic boxing or simply
boxing), olympic country (e.g.:
olympic china). The OneBoxes are also available on Google's mobile search site, where you can search for
similar keywords or use
a list of sports.

When you search for [summer games], there's an ad that asks you to "stay up to date on the summer games using Google". The ad links to
a page that promotes the iGoogle gadget mentioned above,
a YouTube channel with news from Associated Press, NY Times, EuroNews and a Google Maps mashup that shows the locations of the Olympics events.
Google Blogoscoped points to
a Chinese version of the landing page, which promotes more Google services, including the new
Google SMS Alerts (
English translation). The new service, available only in Chinese, sends free text messages with information about weather, medal counts and results.
