conventional advertising simply no longer works, not unless you're a fortune 500 company with deep pockets.
Yellow pages ads cost way too much (and don't work)
Print ads only work if you're pitching to the over 60 crowd.
80% of all twitter tweets are from a mobile device (cant do that without disposable income)
People online have money (enough to buy something)
People NOT online generally weren't going to be able to buy anything from you... I could go on and on
80% of companies use LinkedIn to hire
Generation Y and Generation Z consider Email to be for old foggies.
You wanna keep your job?
You better hope your company learns how to advertise online.
If they don't, they're going to be extinct.
