Home phone service...I haven't used a landline phone at home for at least a decade, and if it weren't for my cable company bundling it for free with internet and TV I wouldn't have one now. Mobile devices are more convenient and calling minutes are irrelevant these days.

Fax machines...I'm baffled that these are still around, especially with internet and camera phones being more convenient for sharing documents. If you need something more professional, there should be an internet connected version of a fax that supports email or mms.

Broadcast TV (other than news or live events)...it's been a decade since I tuned in live to watch a TV show. DVR was the norm for a time, but on demand like Netflix or amazon are more convenient.
