Denver Post: With the cable industry facing a major shift in how consumers watch TV, Starz said it added 400,000 new subscribers since January 1. Subscribers are up 1.8 million in the 12 months that ended March 31. Its stock price shot up past $40 before closing in after-hours trading $39.33, a record. Lower programming costs, less money spent on marketing and rate increases from various distributors all helped boost revenues, according to the company’s financial report.
