Subliminal Images and TV Advertising - e. g. “Gore a rat? ” • 2000 Presidential campaign the Republicans ran a TV advert. • These words flash on the screen: “The Gore prescription plan: Bureaucrats decide. ” • As the voice-over says: “bureaucrats decide” the word “RATS” in large, white capital letters, fills the black screen.

What the ITC states ITC Code of Advertising. Standards & Practice: `Subliminal’ Advertising 7. No advertisement may include any technical device which, by using images of very brief duration or by any means, exploits, the possibility of conveying a message to, or otherwise influencing the minds of, members of an audience without their being aware, or fully aware, of what has been done. http: //www. itc. org. uk/divisions/ad_spons/ad_standards_code/

So. . . • Would you: – Encourage/discourage the use of Subliminal Images on our site(s)? – How would you deal with it if discovered? – Can we detect/stop its use? – Most of us have disclaimers: • Would you favour ethical statements? • What we we call them? • What would they cover?

The Cookie Monster Conflicts, Ethics and Web Sites

Cookies are: • Information for future use stored by the server on the client; • Typically a cookie records your preferences when using a particular site; • Location of cookie is dependent on the browser • Commonly used to rotate the banner ads so that you don’t see the same ads • Used to “remember” place in a CBL course http: //whatis. com

More about cookies • Users can: – Disable cookies in their browser – Delete cookies from their disk • Cookies expire after a preset time • Not reliable – Don’t make your site rely on them

The Double. Click cookie • Double. Click Inc is a leading internet advertising company • DC operates banner ad servers • DC wants to target its ads by profiling users • DC has accumulated more than 100 million files • Double. Click purchased Abacus Direct Corp - a direct marketing services company that maintains a database of purchasing habits of 90% of US households. (http: //www. usatoday. com/)

The Double. Click cookie: It works like this (I think): • The first time you use a Double. Click’s adserving computer, it sends a cookie to your PC with a unique ID number when you click on a banner-ad; • Every time you clickthru a Double. Click ad, the URL is matched up with your previous visits; • When you e-shop at a Double. Click partner site, then the unique ID is matched to personal details.

So how should we deal with cookies? • How should we deal with cookies? • Does your web sites use them? – How do you use them? • Is it OK to use cookies providing: – it’s used as a placemarker from previous visits – information is collected and collated. • Be upfront. . .

And there’s more Conflicts, Ethics and Web Sites

Advertising on your web site • • Should we host? Do we need to - are there financial imperatives? Does it pay? Where is the content delivered from? (JANET AUP)? • Where does sponsorship stop and advertizing begin? • What’s the model? (“Free service” or “payment”? )

Advertising - We do it already! • We use the web to promote our institution • We have: – mouse mats – screen savers – propriety hardware and software – links to external sites with advertizing

Advertizing Content • • What does it “say” about the site? Do we have content control? Do we want content control? How do we exert control? Censorship vs Freedom of speech Who/What determines what we see? Do we need, yet another, policy for our web sites?

More food for thought • • Use of metatags to entice surfers Logs - how should we use them Browser View Source facilities Exclusion of users: – those with low spec browsers/PCs – through (poor) design. • University freedom of speech policies • Student Union web sites

And so. . . • Do you have content guidelines? • How do you enforce content guidelines? • Is there a procedure at your site for the (rapid) removal of content?

And Finally • Ethical Statements, their value: – They remind us what we’re about. – Once set, we know where we stand. – Our surfers (can) know where we stand. • They emphasise that we’re honest, legal and decent.
