20 years is a long time so you should be right.
I do remember when Stern went to Sirius, people thought it was going to be over for terrestrial in 10 years and look where we are now. Sometimes these things take awhile, especially for car fleets to change over.
Also remember people thinking the stock was going to explode when he went there too. There were people calling up his radio station the day of the announcement like "Howard you made me rich man!!!!" because they bought the stock, but it's been up and down.
