:11:28. > :11:32.uprising, instead you are looking at something that has been part of an
:11:33. > :11:35.elaborate advertising campaign. What's happening here is you are
:11:36. > :11:44.mixing video from camera on the back of this part of the bus stop with
:11:45. > :11:50.preprepared special effects. Get the perspective and the lighting right
:11:51. > :11:53.and you've got an ad that got 4.7 million views on YouTube in less
:11:54. > :11:58.than a week. For this to work, everything the camera sees has to
:11:59. > :12:02.line up directly with this grid. Exact measurements are important
:12:03. > :12:07.because the graphic designers need to know exactly where to put their
:12:08. > :12:11.visuals. The installation itself is quite simple. Along with a camera,
:12:12. > :12:18.there is a 65 inch screen inside the shelter, connected to a single

:12:22. > :12:27.scenarios have been done in advance and that took around three months
:12:28. > :12:31.``Windows seven. We've taken some shots of Oxford Street and have re`
:12:32. > :12:33.version that into a 3`D world and the content we have created when
:12:34. > :12:39.that space uses the environment specifically for that bus stop. If
:12:40. > :12:42.we were going to roll that out across 1500 bus stops around the
:12:43. > :12:46.country, we would have to do that exact same process with all of them
:12:47. > :12:51.and that is where the challenge is. We worked with Unilever on one of

:13:06. > :13:08.make videos work in different lighting scenarios, for example,
:13:09. > :13:15.nighttime or here, dusk. It is a painstaking and elaborate process.
:13:16. > :13:20.As consumers get more savvy about Rand interaction, ads will get more
:13:21. > :13:24.sophisticated. After all, sharing engaging and interesting videos with

:13:31. > :13:34.content is sponsored or not, that's comes second to whether it is any
:13:35. > :13:49.good. On second thoughts, I might walk. Need to promote a product?
:13:50. > :13:59.Service? Or a thing? You need to advertise. It is delicious! Here at
:14:00. > :14:03.the Museum of brands, packaging and advertising, visitors are surrounded
:14:04. > :14:07.by product and commercials from a time when social networking meant
:14:08. > :14:09.attending a debutante ball. Advertisers are finding it
:14:10. > :14:15.increasingly difficult to attract the attention of audiences. More and
:14:16. > :14:24.more TV users are watching on demand streaming services or enjoying TV
:14:25. > :14:32.box sets in great big ad free golds. As more and more TV users are void
:14:33. > :14:36.advertisements modern day madman are designing ways to make products seem
:14:37. > :14:42.desirable. While the practice of product placement has gone on for
:14:43. > :14:54.decades, developers are trying to use technology originally designed
:14:55. > :15:04.for Hollywood block busters to allow them to change things post editing.
:15:05. > :15:07.It allows us to change things that gets distributed to 200 different
:15:08. > :15:12.markets, different brands can be placed in the show as it airs. The
:15:13. > :15:21.good example of that is in Brazil, where we place a Mitsubishi in place
:15:22. > :15:25.of a Bentley in one scene. Some people say it should have been the
:15:26. > :15:28.other way round. The Mitsubishi were specifically being launched in
:15:29. > :15:33.Brazil at the time that the show was airing. In order to add an object
:15:34. > :15:37.after it has been filmed, you had to understand how the camera has moved
:15:38. > :15:43.in 3`D space. Our brains are variable about this, but a computer
:15:44. > :15:46.on its own is a flat in meaningless collection of colours. The
:15:47. > :15:48.techniques pioneered here help computers to automatically
:15:49. > :15:53.understand what is going on in a particular shot, so they know how
:15:54. > :15:57.the camera is moving. Once you know that, you can put the new object in
:15:58. > :16:03.with exactly the right orientation and lighting. Product placement is
:16:04. > :16:07.an example of a hidden method of persuasion. However, in some
:16:08. > :16:13.quarters, more overt tactics are preferred. Online advertising can be
:16:14. > :16:16.very specific and targeted. Advertisers can track what sites
:16:17. > :16:22.users have searched for and visited, tailoring ads as a result of the
:16:23. > :16:26.data gathered. TV is starting to imitate what the online world is
:16:27. > :16:31.doing, and they always say imitation is the sincerest form of flattery.
:16:32. > :16:35.We must be doing something right in the online world, because TV is
:16:36. > :16:39.starting to go towards making ads more targeted and more personalised.
:16:40. > :16:43.Historically, advertising has a work kept pace with the latest advances
:16:44. > :16:47.in technology, whether that is paintball pixels, in order to sell
:16:48. > :16:54.stuff. The manner of delivery may change, but the message remains the
:16:55. > :16:58.same. If you want to get noticed in the
:16:59. > :17:02.tech world, San Francisco is the place to be. It is teeming with
:17:03. > :17:06.young hopefuls, all vying for interest in their latest invention.
