Ok so I’m going with a little different approach and talking about as seen on tv products. I will be mentioning products that were not marketed as toys.
The Red Devil Grill
With an infomercial starring Nick and Mimi who were later known for their Magic Bullet infomercials. These were later recalled.
Did you know/remember this came out in 1998?
Consumer’s Auto Connection
I still have no idea what this product is.
These commercials were both shown during Pokemon a lot.
First Generation: Virgin XXV Years
Now That’s What I Call Music! #1 in the USA.
The Wikipedia article explains it better than I could.
While I waited in anticipation to watch Are-oh-vee I would frequently see these products advertised.
It seems like the motorized successor of the Shiwala that came out a few years earlier.
Banned From Television
Remember this was before the days of youtube. For some reason they showed this so much that there were 2 different commercials with 2 different phone numbers.
Jerry Springer Too Hot For TV
I remember the kids at school bragging about how they watched this video.
America’s Funniest Home Videos Uncensored
I found the commercial on a tape with other things recorded in 1998. Although IMDB says this video came out in 2000.
If you are looking for Marvin’s Magic Drawing Board that is mentioned in this entry about toys.
This is not an as seen on tv product, but this place used to run infomercials locally and they are still in business.
Here is their yelp page.
