"Free download" doesn't state what the download is - it could be a free download of a music clip, a picture, a video, a text file, etc.
Unless you've been living under a rock for the past 10 years, a "podcast" immediately conjurs up an audio file. In fact, the dictionary definition of a podcast is along the lines of: "
A multimedia digital file made available on the Internet for downloading to a portable media player, computer, etc"
So because some people are a bit dense and assume you must have an iPod to listen to them, the BBC has reach out to the lowest common denominator and at great lengths rebrand the naming of audio downloads of shows.
Or do they.......
