Many Olympic track and field athletes have tweeted their displeasure with what is known as Rule 40. It basically stipulates that Olympians are prohibited from engaging in advertising during and shortly after the Olympic Games.

Leo Manzano explains that he has already been forced to take action concerning the rule.

Here is a summary of Rule 40 from London2012.com:

Rule 40 of the Olympic Charter limits athletes competing in the Olympic Games from appearing in advertising during and shortly before the Olympic Games. This helps prevent ambush marketing which might otherwise utilise athletes to create an association with the Games.

This definitely seems like a coordinated effort by track and field athletes.

Non-athletes are also voicing their support for change in this area.

The International Olympic Committee has also given athletes directions on how to use social media. Here is an excerpt from the guideline bulletin to Track and Field Athletes Association:

First and foremost, the IOC does not want social media to take any form of advertising.  Sadly, their definition of advertising is quite strict and it appears any shout-out to sponsors who have supported an athlete cannot happen

Sports business analyst Darren Rovell, who recently was employed by CNBC, also gave his thoughts on the rule.
