Inbound marketing, on the level it's done today, just wasn't possible prior to the digital age. Technology was the key limitation. Advertising on TV, or in your local newspaper, for that matter, had to paint in broad strokes. You could look at demographics and do your best to plan, but ultimately you had no way to connect with customers individually. Ads like that were also imposing on customers. TV commercials or half-page print ads were the price you paid for watching your favorite show or catching up on the news.
Why does this matter now? Well, technology has reshaped marketing once again, this time for the better. Our digital world opens up possibilities that simply didn't exist, even in the relatively recent past. With how fast technology develops, it's important to stay up to date on the latest trends if you want to sustain success.
