Paul Alan Clifford started doing church tech in 2000, when projectors were cutting edge and PowerPoint was the closest thing to worship software that most churches had. He writes a monthly column for ChurchProduction.com, and occasionally for their print edition as well. You can also find his articles in Technologies for Worship, and on ChurchTechToday and ChurchM.ag.
Each week, he publishes multiple audio podcasts and videos on TrinityDigitalMedia.com, his ministry's website.
You can find his books Podcasting Church, Tweeting Church, The Serving Church, Church Video School, and others on Amazon.
