A French court sentenced the woman to a fine of SEK 12,000, Reuters reports.
In connection with the crash, she held up a sign that cyclists got entangled in and the mass crash was a fact.
She also had to symbolically pay ten kroner to the French professional cycling association
The woman held up a sign with the text "grandmother and grandfather".
She leaned forward to join the TV broadcast when the German skier Tony Martin, who was at the front of the group, drove into her and fell over.
The fall caused a domino effect where just over half of the riders crashed, an estimated around 80 cyclists.
Eight cyclists received medical treatment after the crash and the German skier Jasha Sütterlin was forced to withdraw from the race.
