Craigslist moves into another 100 ad markets

Craigslist grew even bigger this weekend by adding a further 100 cities and countries to its roster of mostly free classified sites. In what appears to be the company's single largest expansion, it took on 72 new markets in the States while the international expansion includes 28 countries and cities, such as Pakistan, Portugal, Malyasia, Beirut and Helsinki. Craigslist's free classifieds pose huge challenges to the newspaper industry's major source of revenue. (Via paidContent.org)
