The Social Buzz Top 50 countdown continues with numbers 30 to 21 revealed

The Drum has started revealing its Social Buzz Top 50 – a list of the most influential people in social media marketing.

We asked readers to nominate individuals excelling in social media marketing, with the longlist of nominees passed to some of this year's Social Buzz Awards judges to decide who made the list and the order of the Top 50. Judging was based on leadership and innovation in the sector, as well as the overall contribution made to the industry.

The number one individual will also be named Social Media Individual of the Year at the Social Buzz Awards on Thursday 27 November.

Each day this week, we are publishing teasers with a countdown of who made the list, with the full list – including profiles on each of the 50 – to be unveiled on Friday, 28 November.

Numbers 50 to 41 were revealed on Monday and numbers 40 to 31 were named on Tuesday.

Now, we reveal numbers 30 to 21.
