Mashable: “The movement towards huge got a big boost when the Internet Advertising Bureau recently added some big new formats to its standard ad unit sizes: 300×100 and 720×300. Additionally, even bigger takeover-style ads been seen on many popular websites over the past few weeks, including ESPN, MySpace (MySpace reviews), and YouTube.
Why go huge? Online Media Daily explains YouTube’s strategy: “Many people come to YouTube without having a particular video in mind to view. They land on the home page to search through the site for videos that grab and pull them in.”
And pull them in is exactly what ads of the takeover variety can do – on all but the biggest resolutions, they take up so much screen space that you can’t miss them.”
