Vespula: They did have a Public Relations/promotion plan but it was compromised by the technical problems. They had to throttle back. Technical problems are now solved and they can reinitiate the supporting PR plan? I suspect there may be additional ads.

Yes, I think this is a very reasonable speculation (because it also is my own). I actually expected much more after the first two ads and wondered why the momentum stalled. The sputter tool problem is a very valid explanation.

Encouraging to see the ads being aired again! I wouldn't be surprised if the milestones wouldn't take until the end of Q2 to be completed!
