I think it's typical for most products people buy. I'll do research and compare products/vendors when I'm purchasing a TV, but if I need sponges for the kitchen I'm just going to type "sponges" on Amazon and [most likely] purchase something from the first page of results.

We all purchase a lot more sponge-like products than TV-like ones.

True, but more advertising dollars are spent on TV-like products.

Perhaps I'm in the minority, but I would totally look for sponge reviews before buying them.

You can read the sponge reviews on Amazon:)
