The vital function of a trademark is to distinguish goods and services of one company or individual from that of another, and if the mark does not perform this essential function, it is likely that the trademark will cease to exist and just become a generic term.
Certain trademarks such as Escalator and Cello tape have become a generic trademark and have lost their distinctiveness in the market. People no longer identify the name of the brand with a particular manufacturer, and therefore these names become generic.
Generic terms or words are commonly used in symbols, words or logos to describe the class of products or services. Generic words don't perform the function of distinguishing similar products and services in the same class. For instance, a Cake Shop cannot receive protection for mark ‘Cake shop’ as the mark clearly describes the nature of the store instead of distinguishing it from another.

When people start associating a mark with a group of services or goods, the name stops functioning as a trademark and falls in the public domain, thereby losing its essential characteristic of being distinctive.
The key here is that the public should recognise the trademark as an identifier of only your products and services. If you take certain steps to avoid genericide, it would ensure that your brand's trademarks don't get abandoned.
Once a trademark has lost its ability to perform the function of distinguishing a brand's good and services, it can no longer act as a trademark. The mark eventually becomes generic, despite the fact that a brand might still have rights of exclusive use over the mark.
