I believe the show A.D. triggered the pulse. Maybe the T.D. at the A.D.'s cue. Since Tonight was a 60 network 60 local avail, it was essential to let the affiliates know the break was coming. </div><div><br></div><br><div>

Up until the mid to late '80's, NBC would use that form of alerting stations when to start quad heads (flashing), and then roll (steady) for those shows that weren't pre-recorded in advance and had timings distributed. Normally, MCR received TWXs of all shows with pretty accurate timings. The exceptions were things like: Tonight, Tomorrow, Today, etc.<br><br>(Good catch!)<br><br>Nick Grbac<br>KRON-TV MCR<br><br><br><br><br></blockquote></div><br></body></html>
