Do you remember the 8 track? If you're my age, you remember more chatter than the actual product. "Revolutionizing the music industry" by taking your music with you. Pretty cool.
Now there is the iPod ... take thousands of songs with you and jump to any one in a moments notice.
The reality is, they are the same. They both play music ... one song at a time.
The difference is the reach, frequency, quality, and brand satisfaction. Are you running an 8 track marketing campaign, or do you have a campaign that uses traditional, viral and social mediums?
Evaluate.
Be clear, concise, compelling and creative.
