Clear Channel teams with The Drum for digital advertising experiment on Piccadilly Circus digital screen
The largest screen in Piccadilly Circus is to host questions about digital advertising, run by The Drum in conjunction with Clear Channel.
As part of Advertising Week Europe this week, The Drum will be asking a question every day and looking for respondents to tweet their answers in reaction.
The answers can be responded to using #MonYes or #MonNo - the hashtags will vary depending on the day of the week with Tuesday's response being #TuesYes or #TuesNo.
One question will be asked each day with the results being revealed the following day on the billboards.
The real-time experiment will aim to engage passers by and delegates attending Advertising Week Europe to discover the effect that outdoor digital advertising has on the public.
