Snapchat will be a good way of Online Advertising due to the Geo Filter option which can be used throughout the Press Event evening. Geo Filters are a great way of marketing through other peoples accounts as they post using the Geo Filter and people who follow them see the advertisement.
Another good factor is the fact that, Snapchat allows you to see who has viewed your story, which means you can keep a record of website traffic and who the post has reached.
