text:  Sweeping changes are in store for CNN starting this year. Today, the cable news network's chief executive, Mark Thompson, informs staff 100 jobs, or 3% of CNN's workforce, will be cut. He says the layoffs are part of a broader strategy to compete in the digital subscription business. The CNN executive projects more than a billion dollars in revenue, according to CNN's homepage. Thompson envisions unifying three divisions, U.S. television, international television, and digital.
