The name "Tea Party" is a reference to the Boston Tea Party, whose principal aim was to protest taxation without representation. The protests have sought to evoke images, slogans and themes from the American Revolution. The letters T-E-A have been used by some protesters to form the backronym "Taxed Enough Already".
Commentators promoted Tax Day events on blogs, Twitter, and Facebook, while the Fox News Channel regularly featured televised programming leading into and promoting various protest activities. Reaction to the tea parties included counter-protests expressing support for the Obama administration, and dismissive or mocking media coverage of both the events and its promoters
