You could take this a step further and add channel numbers along the side, replace icons with text which includes some extra info. BAM! You've got a working guide. Makes it real easy to see what's currently on, what's coming next, if it's a rerun, parental rating. All of this without having to highlight a program. You could have a little box at the bottom with the info for the highlighted program.
No offense, but someone coming from an OTA background probably shouldn't be designing these things.
Deep, deep eyeroll on this one. I also come from an XBMC/Kodi background where the amount of content you potentially have to deal with makes any cable lineup look sad and embarrassing. And I know first hand that interest and dedication (and to some degree artistic skill) matters a lot more than a user background.
I can't tell if you are making a sarcastic "solution" by creating a channel guide, or instead are suggesting putting the channel number along the side of each tile/program. I'm guessing you are suggesting the first, in which case, no response, because that response was not requested in this thread.
If it was the second, we could potentially do that. Turn every box into text. It would be unbelievably ugly, but we could do it. Some groups actually go halfway with this, which is what I'd like to do for the "On Deck" page, whenever we build that. Where instead of boxes, one builds a rectangle, with the show image on the left and some text on the right describing the show, it's various statuses, potential conflicts, etc.
I don't know if having that much info (at the sacrifice of images) would be worthwhile on the Discover Now screen. It seems like it would detract from the point of the page, which is to help you discover new content. Pretty much every content discovery source in the past 30 years from Blockbuster stores to Hulu and Netflix home pages have pretty clearly demonstrated that content discovery is at least partially about sizzle. Does the cover and art look good? If so, I shall perhaps dive down and learn more about it. Getting rid of the "sizzle" in a page dedicated to discovering new content feels like not the best advice.
