The campaign will run for the next six weeks - tickets are on sale  until April 26th - with the theme of 'the greatest tickets on earth'.
Organisers Locog have produced 13 different adverts supporting eight  sports with leading British athletes, such as diver Tom Daley and  gymnast Beth Tweddle, among the stars.
"The launch of Olympic tickets is an important milestone for us, and a  key part of our commercial programme," said London 2012 commercial  director Chris Townsend. 
"We need to raise £500 million from ticket sales - this is a key  revenue stream for the costs of staging and hosting the Games.  
"We have developed a fair ticket pricing model, and are confident the  public are as excited about the greatest tickets on earth as we are."
Educating fans about the ticket process is one of organisers Locog's  current biggest challenges. Fans will have six weeks to apply and  oversubscribed sessions will be allocated after a ballot.
Locog want to reinforce the message that tickets are only available  from three official sources, the London 2012 website, short break  packages from Thomas Cook and on-site hospitality run by Prestige  Ticketing.
"We want this to be the greatest show on earth, not the greatest scam  on earth, and we want these tickets to be bought by genuine sports  fans, who want to be part of London 2012," said London 2012 chairman Seb  Coe. 
"I would urge caution, be sure about where you are buying tickets  from and if they are not an official ticket seller, be safe and don't  take a chance."
London 2012 have also produced a series of films,  featuring Olympic gold medalist Jonathan Edwards and comedian Miranda  Hart, designed to make sure fans get the lowdown on how to apply for  tickets.
