Business Research - American Media Companies

I am working with a client in the United States who has a media related product and I need someone to research the Media landscape in the US for me and pull together a list of the relevant media agency people who work in the media industry, the TV Publisher companies in this industry, and the influencers/journalists/commentators who work in this industry. There are three specific segments I'm after; 1) Media Buyers at Media or Advertising Agencies - these people buy TV, Radio, Online media for their clients and I'm after both the Senior employees and management (e.g. CEO, CTO, Media Director, Head of Investment , MD, Digital Lead) and the more junior to mid level staff (e.g. Media Buyer, Account Manager, Senior Account Manager, Account Director, Senior Account Director, Business Director). Here are a few resources for this segment: This is a link to 17 of the top agencies as a starting point -[login to view URL] and here is a list of the Top 10 Media An article on the Top 10 Media Buyers.

I'm only interested in people who are well respected in the industry and have either significant social media followings and/or write for important media publications, blogs etc not for their community paper. This site should help you find the journalists - [login to view URL] The list should be in an excel format and needs to be segmented as above - 1) Media Buyers, 2) Publishers, 3) Influencers, Journalists and Commentators I need the following personal information - name, any social media account info ( e.g. LinkedIn URL, Twitter Handle), a brief sentence on who they are/their work position ( can be taken from their work Bio or LinkedIn / Twitter sites), url link to their blog/website if they have one, the company or publication etc they work for and their email if you can find it. There are thousands of people who work in this area in the US and I'm after a good chunk of them - 1,000+ names. I need this done by EOP Friday 16th October.
