Joris Evers of Netflix emailed me to say:
Spotted your tweets and wanted to let you know that Netflix has not purchased and does not purchase advertising on the Rush Limbaugh show. We do buy network radio advertising and have confirmed that two Netflix spots were picked up in error as part of local news breaks during the Rush Limbaugh show. We have instructed our advertising agency to make sure that this error will not happen again.
I'm going to re-activate my Netflix account now.
