T-shirts are still around and help people represent their individuality though graphics or text. Some say that the t-shirt is the original facebook status update where people could display what they think to a number of people, just like social networks.
According to Google Trends, the word t-shirt is on the decline and when compared to the term social media you can see a cross over point.
This shows that not many people are talking about t-shirt, however when you insert an altered version of the word without the hyphen you’ll notice an increase where you will also see a cross over point. This could be due to a new generation of kids growing into an SMS world where spelling is not exactly important.
