Tobacco-owned brands also offered a narrower range of nicotine options than the vape shops (P=.002) and were less likely to offer nicotine-free e-liquid compared with internet-only and vape shop brands (P values <.001). Finally, 83% (10/12) of tobacco-owned brand websites featured age verification pop-up windows. In comparison, only 50.2% (130/259) of internet-only brands (P=.01) and 60.5% (98/162) of vape shop brands (P=.06) featured age verification windows. Websites surveyed in both 2013-2014 and 2016-2017 became more likely to sell open-system mods (P<.001) and sold an increased number of product models (P<.001), flavors (P<.001), and nicotine options (P<.001). Prevalence of several types of claims decreased significantly, including indirect claims regarding smoking cessation (P<.001), claims regarding e-cigarettes as healthier (P<.001), less expensive (P<.001), and usable in more places (P<.001) compared with combustible cigarettes. Conclusions: The number of e-cigarette brands has not appeared to increase since 2014, even as website messaging evolved, with brands owned by tobacco companies and vape shops pulling in opposite directions. Brands owned by tobacco companies offered a limited range of e-cigarette products, whereas brands owned by vape shops emphasized a panoply of flavor and nicotine options. Furthermore, the Food and Drug Administration’s regulatory action may influence the types of e-cigarette products offered and the market shares of various companies.
