Every Thursday morning, find all the stories you need to know about your friendly telecommunications giant in the Comcast Roundup.

Seventeen more cable TV networks have agreed to put their content on Comcast’s TV Everywhere, the proposed online video service that would be offered to subscribers only. That brings the total to 23, according to the Associated Press.

Though some public discourse has remained skeptical of the authentication model, Comcast has continued to move forward with its unprecedented experiment of paid content on the Web.

HBO is in that number of participants. The cable channel recently announced it will put at least 750 hours of its programming on the service scheduled to be rolled out for 5,000 trial subscribers in coming weeks, as reported by the Philadelphia Business Journal. That’s nearly as high profile as the thunder heard after CBS announced it was following suit, as reported by MediaMemo, which followed Time Warner becoming the first big fish in the pond with Comcast. Others, like Starz, added their own buzz.

Details on the security of the system aren’t yet clear, but it’s unlikely 23 networks, including major players like Time Warner, CBS and HBO would join so quickly if something wasn’t clear.

After the jump, more social media praise, a Comcast technician turns to crime and six other stories for the faithful.
