Here is a recently published book that I have just been made aware of.  The book is Watch This!:  The Ethics and Aesthetics of Black Televagelism.  I have not yet read the book, but from the reviews, it seems to be a worthwhile work.   At first glance, it does not appear to be a theological critique as much as a sociological and religious one.  Yet, even in this it may prove beneficial and instructive.  I also came across an interview with the author that may shed a little more light on him and his motivation for the book:

Ten Questions for Jonathan Walton on Watch This! The Ethics and Aesthetics of Black Televangelism

What inspired you to write Watch This?

My interest in African American religious broadcasting came from what I perceived to be the gaps in the fields of African American religion and Religion, Media, and Culture. For the most part, scholars of African American religion in general and black theology in particular theorize about Afro-Protestantism in America according to a particular historiography that privileges liberal Protestantism in general, and civil rights motifs in particular. But the prevailing narrative of the freedom-fighting “black church” is in many ways inconsistent with a number of African American Christians whose view of the faith is informed by Trinity Broadcasting, the Word Network, and Streaming Faith.com. Just the same, for sociologists and communication theorists who have examined the world of evangelical religious broadcasting, it is predominantly framed as the domain of the white, religious right.

This book, then, is my attempt to illumine, unpack, and interrogate the theological and social orientations of prominent black religious broadcasters in order to understand them as a source of attraction and ethically evaluate their dominant messages.
