Right, so personally I feel BB is in desperate in need of a complete revamp! From logos to location to presenter. Over the next while ill be posting all my ideas here in this thread. I'll also be posting my timetable for the show and a basic plan for evictions aswell as a website.
LOGO
The logo is very basic. I think the novelty of having an eye has kind of worn off but it is critical to the identity of the show. So I prose the actual text with the eye included become the "Official" logo, and the plain eye template be used partially but not as the logo itself. It will basically be a secondary logo.
Pre-Launch Advertising
The show will be advertised heavily from 3 weeks before the launch. The main emphasis will be on trying to make the show have an "event" like feel back. Big Brother basically relies on the word of mouth success so the advertising campaign will take place in all forms of media. The ads will focus on the fact there will be a complete overhaul of the format- Which will later be posted.
