Social media and television broadcasting have a number of connections and interrelationships. In the 2010s, social media technologies and websites allow for television shows to be accessed online on a range of desktop and mobile computer devices, smartphones and smart TVs . As well, online users can use social media websites to share digital video clips or excerpts from TV shows with fellow fans or even share an entire show online. Many social media websites enable users to post online comments on the programs—both negative and positive—in a variety of ways. Viewers can actively participate while watching a TV program by posting comments online, and have their interactions viewed and responded to in real time by other viewers. Technologies such as smartphones , tablets , and laptop computers allow viewers to watch downloaded digital files of TV shows or " stream " digital files of TV shows on a range of devices, both in the home and while on the go. In the 2010s, some television producers and broadcasters are encouraging active social media participation by viewers by posting "hashtags" on the TV screen during shows; these hashtags enable viewers to post online comments about the show, which may either be read by other social media users, or even, in some cases, displayed on the screen.
