Online advertising uses the internet to deliver marketing messages through website, microsite, web banners, rich media ads, social network, email marketing, blogging, online video, and SEO, etc.

Digital advertising extends beyond the World Wide Web. Mobile advertising obviously falls under the digital umbrella, it doesn’t get any more personal as your phone is with you 24/7.

Digital advertisng extends further into traditional media.

Digital TV offers interactivity and TV commerce opportunities.

Digital Radio offers over the air music download opportunities.

Outdoor digital billboards demand much more attention.

Interactive video projection and holographic effects produce better WOW effect at live events.

We might have come to the end of the beginning phase of online advertising but I think  we have only just entered the beginning phase of digital advertising.
