Social media has given sports fans a new way to unite and add fuel to heated rivalries.

So fans of the San Francisco 49ers have joined together using GoFundMe.com, a crowd-funding website, to pool money for a billboard in downtown Seattle supporting the 49ers. The group was formed by Aasheesh Shravah, who said the decision stemmed from a recent incident in which Seattle Seahawks' fans raised funds in a similar manner to have a plane fly a Seahawks banner over the 49ers' Candlestick Park stadium before a game between the two teams.

"After lots of discussion … a lot of us have decided to counter the Seahawks' fans flying a plane with their banner around Candlestick by placing a billboard showing our 49er pride in Seattle," he wrote on the group page.

What the billboard will display has yet to be determined, but a theoretical design posted on the GoFundMe page shows the 49ers' five Super Bowl trophies superimposed on an image of "The Catch," a famous play that sealed a victory for the team in the 1982 NFC Championship game.

Shravah initially aimed to raise $7,000 to cover the cost of maintaining the billboard for one month, according to the group page. The Seahawks will play their final regular season games and possibly a playoff match in that time frame.

Shravah said he has collected more than $8,500 in donations through 11 days of fundraising. All donations given after the group reached its initial goal will be given to a charity on which the members will vote, he said on the GoFundMe page.

Shravah did not respond to ABC News' multiple requests for a comment.
