Play DJ was a text-in quiz show which aired weekdays from 6 pm and weekends from 10 am on the now defunct British ITV Play channel. The show replaced a similar programme called ITV Playalong which was aired as filler on ITV Play when no live presented programmes were being aired (and continued to do so late-nights until the channel's demise). Viewers could also send in messages to be displayed on-air in a chatbox.
