Jonathan Leess, president of CBS (NYSE: CBS) Local TV’s digital media group, is packing it in at the end of the year, TVWeek reports. Leess was tasked with helping shift the culture of CBS (and its local stations) from just producing TV content to a constant stream of TV, mobile and Web-based news. During his tenure, visitors have gone from watching fewer than 1 million video streams per month to 25 million per month, and one of the initiatives he spearheaded was a hyperlocal ad network. CBS didn’t immediately announce the name of his replacement (or whether they’d be naming one at all) and Leess said he expected to continue working in digital media.
