Understanding "Bumps & Teases" in News Programs

[chantella28]

I have to analyze a news program for a media technology class, and it asks me about the bumps and teases... I've searched google but I can't seem to come up with a definition of what these terms mean, could anyone help me out?

'Teaser' is likely a piece of a program designed to catch the interest of a viewer. - see http://advertising.utexas.edu/research/terms/

Not sure about bump - but this is from http://www.trentu.ca/trentradio/spon/spn_jarg.htm

Bump Rates - The costs that must be paid by an advertiser to secure a commercial position previously sold to another advertiser. To "bump" the previous advertiser, the new advertiser must pay a higher rate. However, the previous advertiser had to have (in most cases) purchased the slot at a "preemptible" rate.
