Public relations
 (
PR
) is an important part of marketing, and involves managing 
a target market’s (or the general public’s) perceptions of a brand or organisation. 
Techniques used in PR include:
Providing news stories to the press, etc. as a cheap and effective way of getting 
publicity. News media are often happy to have someone else do their work and 
provide them with ‘stories’, such as new technological breakthroughs being launched 
into the market, news about celebrity bosses, awards given and received, charity work, 
events, etc.
Appearing as a guest or an expert on TV talk shows, etc.
Putting the right ‘spin’ on bad news stories, for example managing a recall of a faulty 
or dangerous product. Reassuring the public and being seen to act responsibly.
Publicity stunts and other events designed to attract attention.
Lobbying decision-makers, for example politicians.
Collateral literature, for example brochures, websites.
A 
press office
 is a part of an organisation which deals directly with the press 
and other media, especially in relation to PR. It is responsible for producing and 
distributing 
press releases,
 i.e. messages that the organisation would like to be 
communicated, presented to make it easy for the media organisation to turn into a 
story. For major events (such as a new product launch), the press office may supply a 
full 
press pack
, consisting not only of a press release but also samples of the product, 
photos, interactive CD-ROMS and other promotional literature, etc.
