The campaign, which launches this week and is called "Everything to play for', is set to include marketing at stadiums including match-day programmes, TV advertising, an online competition and local and national level PR.
Stewart Regan, championship director, said: "The 'Everything to play for' campaign will allow us to demonstrate that the championship is one of Europe's major league competitions, from exciting, competitive action throughout the season, to a heritage dating back to 1888 and clubs that are at the heart of their communities."
The Coca-Cola Championship was created last year as the new name for the Football League's Division One.
Key messages in advertising include its high attendances of 9.8m last year, a 10% rise on the previous year, and its array of home grown talent.
Paul Rawnsley from the sports business group at Deloitte, which conducts an annual review into football finances, said: "Governing bodies need to implement innovative marketing of competitions to ensure they are more attractive to supporters, broadcasters and sponsors.
"The 'Everything to play for' campaign shows the Football League is willing to do that by focusing on what the championship has to offer."
Clubs involved in the championship, in which three teams gain promotion to the more lucrative Premiership League, range from former Premiership stalwarts Southampton FC and Leeds FC to minnows including Brighton & Hove Albion and Luton FC.
