I am now reading Let You Go by Clare Mackintosh, and this paragraph caught my eye. The character talks about Post-Its. Everyone reading it would know what Post-Its are, even if they are not actual Post-Its. Post-Its are an example of a brand name that has become the informal name of a product (like BandAid or Hoover or Xerox). And they are also an example of a product created by accident.
Post-its are so popular that Microsoft launched a version for computer screens. These are called Stickies and can be configured to remain visible on the screen over a screensaver.
I enjoyed that extract —
