Cell phone usage has also become a benefit for social media marketing. Today, many cell phones have social networking capabilities: individuals are notified of any happenings on social networking sites through their cell phones, in real-time. This constant connection to social networking sites means products and companies can constantly remind and update followers about their capabilities, uses, importance, etc. Because cell phones are connected to social networking sites, advertisements are always in sight. Also many companies are now putting QR codes along with products for individuals to access the company website or online services with their smart-phones.
