In many cases, the step-family is large and full of children causing situations such as sibling rivalry, rooming, falling in love, and getting along amongst the children as popular plot-lines. This premise gained traction with the 1968 films Yours, Mine and Ours and With Six You Get Eggroll and the 1969 launch of the television sitcom The Brady Bunch. Some contemporary family sitcoms have made the blended family sitcom more popular with the TGIF show Step by Step bringing about other shows such as Aliens in the Family, Life with Derek, Drake & Josh, and the short-lived NBC family sitcom Something So Right.

It is also referred to as methylphenidate transdermal system (MTS). It is approved as a once daily treatment in children — ages 6 to 17 — with ADHD. It is mainly prescribed as a second-line treatment when oral forms are not well tolerated or if people have difficulty with compliance. Novens original FDA submission indicated that it should be used for 12 hours. When the FDA rejected the submission they requested evidence that a shorter time period was safe and effective, Noven provided such evidence and it was approved for a 9-hour period.Orally administered methylphenidate is subject to first-pass metabolism, by which the levo-isomer is extensively metabolized.
