What is Advertising ?

Ive become really interested in Advertising so I decided to write a little about it first of all what is advertising?  and its  a form of marketing communication used to encourage, persuade, or manipulate an audience (viewers, readers or listeners; sometimes a specific group) to take or continue to take some action. Most commonly, the desired result is to drive consumer behavior with respect to a commercial offering, although political and ideological advertising is also common.  Literally every where you may see advertising especially on TV that were people get persuaded the most. Haven't you seen that new phone commercial on TV and you want it just because you saw it and now you want to have it. Advertising is very important in the TV and radio industry.
