A few years ago, your only gift choices for your geeky friends and family were men's and women's T-shirts, but that's all in the past.
Geek culture has become mainstream.
"I would say that during the last five years, the geek chic business has grown tremendously," Ed Labay, vice president of merchandising at Hot Topic, told CNBC. "So many people and companies are trying to find their way into it."
Brands are no longer peddling T-shirts and action figures. Companies have adapted to serve customers in a wide variety of categories, including apparel, housewares, toys and health and beauty.
From "Game of Thrones" to "Star Wars" and "The Walking Dead" to "Halo," today's geek is more diverse than ever.

Here's a look at some of the hottest geek gifts to hit shelves for the 2016 holiday season:
Gwen Stacy has become an unlikely hero in the Marvel universe after an alternative story line saw the female character bitten by a radioactive spider instead of Peter Parker.
Spider Gwen has inspired a slew of merchandise including posters, figurines and even clothing.
The Spider Gwen jacket created by Her Universe and distributed through Hot Topic will set you back about $50 and features the super heroine's signature purple and turquoise spider web print sleeves and a hood.
"The business of pop culture has exploded," Labay told CNBC. "Expressing your passion for these stories and characters, and being able to do it in a more fashionable way, or at work, has brought a whole new level to being a fan. This fashion allows fans to embrace their own individual fandom interests in a way that could never be done with a basic T- shirt."
