ESPN has acquired Racing-Live, the parent company of F1-Live, the leading Formula One news site on the web. For the 2010 F1 season F1-Live has been re-branded as ESPN F1 There's a new site design but the content is pretty much the same as it was under Racing-Live's ownership.
The mobile edition of ESPN F1 has the full site's newsfeed, which is updated several times a day with the latest news, rumors and gossip from the F1 circus, plus photos, videos, race results, calendar, driver and constructors championship standings, team homepages, driver profiles and live commentaries on race days.
The site uses browser detection and adaptation to provide an optimized experience to the iPhone, Android and other advanced phones as well as basic feature phones. The mobile site is available in English and French.
F1-Live was my favorite site for F1 news and live coverage and it so far it looks like as good as ever under ESPN's stewardship.
The news is not so good for the other two members of the Racing-Live family of sites, Rally-Live.com and Moto-Live.com, which seem to have been shuttered by ESPN.
