Senior Citizen here. Went to brick and mortar store in Dublin CA to obtain one of the channel lineup brochures that used to be handed out freely that had fairly large print and the channel logo alongside the number. Was told that "because of the Corona Virus, Comcast is no longer printing them but you can go online and print one out."
I told her I'd already done that; that the print is small and no station icon is displayed next to the number, making the identification of the unknown channel number for something like ESPN2 in the Bay Area a laborious endeavor.
Why don't you improve the layout of your online channel lineup to make it brochure quality, with larger, user-friendly print and logos alongside the channel number for faster identification? that would not only solve this problem handily, but would improve customer relations and cost very little to do.
