Is there a standard fake company, product, brand, etc. to use in example text?

I need to build something like

Please enter a company and product you would like to study. E.g. you can enter "Apple" and "iPhone."

But I don't want to implicitly promote any company or product here, including my own company or its products, competitors, random other companies, etc., and I don't want to have to maintain this example as the old becomes obsolete and the new becomes in.

"Acme" may be an example, of American cartoon lore. I still would need a product example that isn't too, you know, violent and I'm not sure this internationalizes well.
