Since the new terminology reflects advances in science and technology, a lack of French terms may indicate a lack of scientific and technological progress. Mass communication and audiovisual technologies are powerful forces in language change. Politicians, journalists, entertainners, commercials spread new words and expressions, as well as their lexical idiosyncracies. Some call it barbarism, others innovation. For a linguist, it is simply the sign of a healthy language.
Advertising is particularly influencial.
Sometimes the slogans are so successful that the new words or the new meaning to a word or expression are better remembered and imitated that the product to be sold by the ad. Advertising may also introduce syntactic changes by, for example, using a transitive verb as an intransitive verb. Franglais is frowned upon by some and embraced by others. Time will tell whether it will survive or not.
