Comcast sent us this statement on the ads, which explains why only some people are seeing them at some times, and how they’re here to stay:
“We’ve added informational ad banners that provide details about television and VOD content on the lineup. These banners will appear periodically on the bottom of the guide in certain markets and will provide details about the functionality of their guide and digital cable service (examples include: setting reminders, recording shows, or using features, like Parental Controls and Favorites). Other cable operators use similar features.”
So basically, they’re like an on-again, off-again, girlfriend who cruises in through town every few days. Except without the dry humping, or even, some decent snuggling.
