If your on hold content, well, sucks, callers are going to call you out on it. Twitter Feedback is hardly new, but there are certainly a lot of people tweeting with the hashtag #onhold who will tell you a thing or two about what they like, and what they don't, while they're waiting to hear from a company. Maybe you'll be surprised to see just how grim it can be... check out this sampling of tweets to see the good, the bad, and the UGLY.
It's a panoptic experience, being on hold while listening to someone singing about being on hold. Depending how long it takes for someone else to join the call, you could be listening for awhile. The music builds as time goes on, culminating in a spoken verse that begins: "Well, let me tell you all a story / about a man who was on hold all day..." This unusually self-aware song is the default music for a conference call service called UberConference, where "I'm On Hold" plays on a loop for anyone who calls in early, on almost every call that doesn't start exactly when it's scheduled to (or doesn't ever start at all). It's selected by nine out of ten call organizers, and plays over a million times per month, says Craig Walker, CEO of Dialpad, owner of UberConference.

-When callers are presented with On Hold Messaging vs. silence or a radio commercial they will stay on hold longer, they are more likely to exhibit interest in the product advertised, they are more likely to retain information, and they are less agitated.
