Using more than one marketing channel to promote a brand has been around since the first newspaper was published. Old school marketing included yellow pages, newspaper, radio, TV, magazines, POP, direct mail, cold-calling, sponsorships, and tradeshows. Amazing when you realize that these are still in use today. Some of these techniques don't work for every brand or company, but every successful brand uses more than 2 of these to reach their target audience along with a company website.
