CBS News Radio is shutting down tonight after nearly a century on the air.
The storied service started in 1927 and gave rise to such icons as Douglas Edwards, Walter Cronkite and Edward R. Murrow.
Together, they and their colleagues brought history into our homes:
From the liberation of Nazi camps in Germany, to the assassination of President John F. Kennedy, to the deadliest attack on American soil, 9/11.
The company announced the closure in March, blaming what it called "challenging economic realities."
To borrow Mr. Murrow's famous phrase, we wish everyone at CBS News Radio one final "Good night, and good luck."
