The document discusses the evolution of mobile technology and its impact on consumer behavior. It notes that in 1983 the first commercial mobile phone call was placed using a phone that cost $3,995 and weighed over 2.5 pounds. Meanwhile, technology has improved dramatically while prices have decreased significantly. The future is no longer about consumers using computers but rather using mobile devices everywhere - to check email, look up showtimes, fill prescriptions and more. Mobile access now accounts for over half of all internet traffic and there are more mobile devices than people. As a result, marketers must understand how consumers use mobile throughout the purchase process and across different experiences like awareness, consideration, intent and advocacy.
