logo necessary?

In my quest to find out if the logo is dead, I googled comparable phrases:
Found one article here

"One reason is people process images in their mind more readily than only words. A logo is a visual stimulation that jumpstarts the audience's memory, leaving a greater impression than words alone. It is the simplest and most direct way to promote your business presence. Think of it like your "what we're about" statement without the long-winded"

"Studies indicate that the average child can recognize and identify over 85 corporate images, but only a handful of species of birds. Clearly, this is the result of many successful advertising campaigns and some effective logo designs."

"Another important reason to have an excellent logo design is to raise the impact of your website and/or product. A professional, eye catching logo immediately establishes an impact and the perception of a higher level of credibility. Conversely, a poorly designed logo can do irreparable damage to your corporate image. After all, in e-commerce, your site is your store. In the "real" world, it would seem doubtful that you would invite your potential clients into a dirty, grungy store and expect them to buy something from you. So, make your customer prospect's first impression a good one with a nice, professional logo!"

Whilst this is all true, we are not using the logo as an advertisement, simply a way to illustrate the brand. What we hope is that the tapes sell themselves, not us pushing the tapes.
