You can’t watch television—or TV ads—without seeing a conspicuous hashtag in the lower corner of your screen.
And while Instagram, Facebook and Google+ have incorporated hashtags with different levels of success, for most people hashtags are synonymous with Twitter. While hashtags are the most popular example, a lot of businesses do other creative things on Twitter to engage their customers.
1. Comedy Central’s #trumproast
Before hashtags were prevalent, it was unheard of to display a hashtag on the screen during a television program. To promote the “Roast of Donald Trump,” Comedy Central displayed the hashtag “#trumproast” on-screen. This resulted in 25,000 tweets during the initial transmission and drove Comedy Central’s television viewership higher than it had ever been for that time slot.
