What is new about advertisement?
There is nothing new but there is trend towards cost-per-click to cost-per-action. Cost per click is that when someone click your advertisement you have to get payment but cost-per-action is that you don't pay until you get action which someone click your advertisement, go into your homepage then the person buy your product, which you advertised, then you have to get bill from ad agency. Another thing is display advertisement which is simpler than banner ad, although display ad is one of the banner ad. Anyway, it appears same place, does not need to contain image, such as picture, video etc and you can narrow to aim your target.
Social media already began one of major advertisement place. There is no more just making connection. You can advertise there and select particular targets by age, location etc. Also using EVENT, if somebody is not your friend or fun but you can inform your event and or campaign.
Mobile devices, such as smartphone, are newer trend marketing. Companies create specialised webpage for mobile phone. They send message like email but that is different from email because people will read it wherever they are. Additionally, proximity marketing that when user is close to target or specific area, advertisement is automatically sent to them. The users get the special information, such as event infor, bargain etc. Moreover, magazine and paper advertisement can take users onto your mobile webpage by using QR code, like bar code, which contains some information about your product or service.
In my opinion, it is up to your purpose, goal whatever. If the trends is suitable your campaign, you should jump on the bandwagon but otherwise you should not. That's it.
