Top Christian Albums is a weekly chart published in Billboard magazine that ranks the best-performing Christian albums in the United States. Like the Billboard 200, the data is compiled by Nielsen Soundscan based on each album's weekly physical and digital sales, as well as on-demand streaming and digital sales of its individual tracks. The chart was introduced on the magazine issue dated March 29, 1980 under the title "Best Selling Inspirational LPs". The current name was adopted on August 16, 2003, in an effort to "streamline" chart titles. The first number-one album was Candle's Music Machine. Amy Grant's Age to Age, released in 1982, topped the chart for 85 consecutive weeks , the longest for any album on the chart.
