Internet Broadcast Corp., a one-stop shop for global news, is making the most of broadband video. The Montreal-based startup that racks up more than 4 million hits a month at ibctoday.com has content-sharing agreements with leading news organizations such as Fox News, the BBC, and the Associated Press, offering viewers access to both national and international content.
