 The program was created in 1974 by Garrison Keillor, who hosted it until 2016.
 It airs on Saturdays from 5 to 7 p.m. Central Time, from the Fitzgerald Theater in Saint Paul, Minnesota; it is also frequently heard on tours to New York City and other US cities.
 The show is known for its musical guests, especially folk and traditional musicians, tongue-in-cheek radio drama, and relaxed humor.
 Keillor's wry storytelling segment, "News from Lake Wobegon", was the show's best-known feature during his long tenure.

 He was the engineer for Garrison Keillor when the latter began his early morning radio show from the St. John's University, Collegeville, Minnesota studio.

 Keith was one of the primary sound effects performers for the radio show "A Prairie Home Companion" and was often an actor in sketches written by Keillor.

The Fitzgerald Theater is the oldest active theatre in Saint Paul, Minnesota, and the home of American Public Media's "A Prairie Home Companion".
 It was one of many theaters built by the Shubert Theatre Corporation, and was initially named the Sam S. Shubert Theater.
 It was designed by the noted Chicago architectural firm of Marshall and Fox, architects of several theaters for the Shuberts.
 In 1933, it became a movie outlet known as the World Theater.

The live weekly radio variety show, A Prairie Home Companion with Chris Thile, whose title indicates the new program host, musician Chris Thile, derives from the historic "A Prairie Home Companion with Garrison Keillor" ("APHC") radio show, where the changeover in the onstage hosting and program began on October 15, 2016.
 Thile, an American virtuoso mandolinist and singer-songwriter, had a two decade history with "APHC" and is known for his work in the folk and progressive bluegrass groups Nickel Creek and Punch Brothers.
 After two unprecedented guest host spots in 2015, Keillor decided on his successor, featured Thile as host again in January–February 2016, and fully ceded his hosting role to Thile in the October 2016 performance at the Fitzgerald Theater in St. Paul, Minnesota, continuing as the show's Executive Producer.
 As of 1 November 2016, the new program presents expanded musical and comedic elements, retaining the template of the earlier program (e.g., its most recent acting and sound effect cast, and "sponsorships" from faux companies), but without such features as its earlier signature "Lives of the Cowboys" series and "News from Lake Wobegon" monologue.
 Early reviews of the new program have been uniformly positive, focusing on the remaining familiar elements and on the new music and expanded musical focus brought by the new host.
Lake Wobegon is a fictional town created by Garrison Keillor to provide the setting for the long-running radio broadcast, "Prairie Home Companion".
 Lake Wobegon is also the setting for many of Keillor's stories and novels.
 It is described as a small rural town in central Minnesota, and it is peopled with fictional characters and places, many that have become familiar to listeners of the broadcast.
 The events and adventures of the imaginary townspeople provide the prolific Keillor with a wealth of stories, that are humorous and at times touching and thoughtful.
Based in St. Paul, Minnesota, APM is best known for the distribution of the popular weekend program "A Prairie Home Companion" and the national financial news program "Marketplace".
